Blocks all users on a following/followers page.

Image from store Twitter Block Chain
Description from store Reduce the damage done by retweeting and dogpiling. Simply navigate to a user's followers/following page and activate the extension by clicking the icon next to the omnibox/address bar. The extension does not block users you are following, or re-block users that have already been blocked. You can also export and import lists of followers in a special format. If an abusive user has blocked you, you can use the export function to retrieve the list of their followers/followings after logging out, and then import the result after logging back in to Twitter. View blocking receipts and add protected users by right clicking the extension's icon and choosing "Options."

  • (2021-05-11) Oriana Sosa: It's not working. At all.
  • (2021-05-10) Auie Bvxc: It works. I have been able to block 400+ accounts in seconds. That said, it causes my Twitter to crash and I have to restart Chrome for me to be able to use Twitter again. Didn't need to delete any cache and cookies though so that's okay, I guess. But I still wish I didn't have to restart Chrome and relog to Twitter every time I want to run the extension. Update: I used mobile.twitter and it didn't crash for me for a few tries so that might help other people using this extension. Also, I just noticed that after a few hundred blocks, there's an error and so subsequent accounts on the list are not blocked. I wish they updated this extension.
  • (2021-05-10) Seth K: Causes twitter to lock me out every time I use it. Useless.
  • (2021-05-04) danistor: error + forced log out
  • (2021-04-29) Richard Reed: Breaks Twitter once it's beeen run. Have to clear cookies after using the extension just to log back in. Seems to max out at 500 accounts at a time.
  • (2021-04-28) Daniel Scarpa: DO NOT USE! Ran this on one account. It blocked a handful of people, gave me an error message, and now I can't use Twitter on Chrome anymore. AVOID AT ALL COSTS!
  • (2021-04-21) Zed: Works good. Just remind yourself that twitter stops you from excessive actions if it detects its a bot/spam so just delete cookies, use mobile.twitter and keep cycling when you get an error
  • (2021-04-18) Sedatcan O: Literally worked perfectly the first time, blocked 170 accounts in a few seconds.
  • (2021-04-18) Traveler Of The Multiverse: It works, but not well. It crushes twitter.
  • (2021-04-10) Deerelly x: It actually broke my twitter webpage
  • (2021-04-09) Justine Houyaux: Fantastic idea, terrible execution. Stops working after blocking 60 followers, need to clear the cache each time, then log in to Twitter again. At this rate, I'll probably achieve similar results by blocking them one by one.
  • (2021-03-29) Jennifer Zeppa: It used to work perfectly but now it crashes my twitter every time I use it and I have to clear all my history data and clear my cache just to be able to log into twitter again.....
  • (2021-03-23) Cecilia Jahee Suh: 1회용. 일단 돌리면 에러나는데 차단은 됨. 로그아웃 문제.
  • (2021-03-20) calicorn: Works sometimes. Logs me out immediately after use and requires my browser's history to be cleared. Can't be used on larger accounts, either.
  • (2021-03-13) Rob W: Doesn't work, just tells me there was an error each time and refuses to block any accounts
  • (2021-03-10) SwordMP3: It logged me out of my accounts and wouldnt let me into twitter. I thought it hacked my account for a good 5 mins. It also did not work to block anyone on a page.... seems like a scam bruh idk
  • (2021-03-09) D. Wilson: It works okay, but only okay, in that it will definitely throw errors shortly after starting. The sweet number for me is about 700 before it starts having issues, but a couple passes got everyone blocked and it's still much easier than doing it manually.
  • (2021-03-09) breioom: Great idea, but as others have said, it apparently doesn't want to function...at all?? Navigated to a person's page (with 6.7 followers) and hit the Run Block Chain button. ...No response. Kind of embarrassing.
  • (2021-03-09) Robin den Hollander: Crashed my entire twitter for chrome. Only get "something went wrong try again" messages for every page of all my accounts. Cannot log out of my account or log in with another account. Clearing your twitter cookies fixes this problem, but that's WAY more hassle than it needs to be.
  • (2021-03-07) OurHands AreTied: Despite what some other reviews have said, it definitely works. It didn't until I cleared my cookies etc., and that's what you have to do to clear big lists of people- every 2000 people or so it'll say 'error' and then it'll log you out, but when you clear cookies, it works perfectly again.
  • (2021-03-02) Holly Warde: Blocked 1023 accounts after being targeted by a transphobe and their followers. Had to run twice, and logged me out twice too, so knocking a star off for that, but otherwise a big help.
  • (2021-02-26) Syah: The extension used to work for me before but now it's just broken. Logged me out of my account when I try to use it and still didn't work when I log back in until I deleted my cookies. I have to give it 1 star for now.
  • (2021-02-25) AJAX: crashed my entire twitter, kept getting "something went wrong" no matter what page i went to on it. wont let me log out and only works on incognito mode now? probably have to clear my cookies now but ...
  • (2021-02-25) 异乡人: 跑了一下登不上推特了
  • (2021-02-22) Isabella Limbert: Works pretty well! Be sure to refresh your cache/cookies before logging back in, helps with errors. One thing I would love to be added is to be able to run a blockchain on someone who has already blocked you. This would make life a whole lot easier for me. Thanks!
  • (2021-02-20) Liam Robertson: Not working.
  • (2021-02-16) Keir Strickland: Simply doesn't work at all
  • (2021-02-15) Silver Z.: needs serious fixes after using it, the website wont load and we have to clear out the cache
  • (2021-02-02) Elle W: it works, but only if the followers list is small. however, after running the chain block, chrome would not load the twitter page. to get chrome to load twitter again, cookies and cache must be cleared. i wish this extension also has the option of blocking people who liked a particular tweet.
  • (2021-01-28) Goran Beg: Hi! Very cool extension! Can we expect newer version?
  • (2021-01-22) Ruth Cornock: Nothing happens. Tried using it, absolutely nothing happened in the slightest.
  • (2021-01-21) Jaguar: 2021/21/1 writing review on this date. it worked perfectly fine. thank you so much i was finely able to remove all my twitter followers at once.
  • (2021-01-18) C C: Put simply, this just doesn't work.
  • (2021-01-17) Jimi chuuu: It was okay since it was blocking hundreds of users at the same time but the issue is that I am planning to block multiple users with more that or at least 10k followers. An error always appears whenever it reached 579 blocked users. And after that error it logs out my account and I had to close the browser and clear cache. It's a bit of a hassle. It may only be useful if you're blocking accounts with hundreds of followers but if more than that its a hassle its disappointing. I even updated my chrome but it still occurs.
  • (2021-01-06) Lionnek: It works, but everytime i run a block chain i can't access my account afterwards. I need to delete the extension and restart my PC because otherwise i can't even log in on twitter! I thought it was a twitter issue, but the app worked just fine and i was able to log in with incognito mode, since the extension doesn't reach it. So the extension does its job, but unfortunately it brings me more problems than solutions ):
  • (2021-01-05) Marie Grubbs: Doesn't work. Nothing happens when I click "Run block chain."
  • (2021-01-04) Deanne Swaringen: It constantly crashes my Twitter page and I have to clear cookies/cache to fix it. It's annoying and defeats the purpose of even downloading this extension.
  • (2020-12-30) Graham Kerr: on first run i got booted out of my account and can't get back in...
  • (2020-12-26) jose omuru: La gente no tiene ni idea de como utilizar la extensión y en lugar de buscar como funciona prefieren votarla con una estrella por que no la entienden... Normal que luego salgan en las elecciones lo que sale
  • (2020-12-23) Roz Konieczny: Yeah, I installed this because I've been having a problem with transphobes/gender critters on twitter and I wanted to be able to just mass block them so I wouldn't have to see them anymore... And when I tried to use it, even if I let it sit, it wouldn't detect any accounts -- then it would log me out and after logging back in, I couldn't access twitter at all (everything said "there was a problem... " and wouldn't load) and continued until I cleared all my cookies related to twitter... really disappointing because it would have been a really useful extension to make my twitter experience safer...
  • (2020-12-18) Jake Underwood: Barely works. And if it does you have to re-authorize through two factor authorization.
  • (2020-12-17) Salmon Run Around: It works but it always logs me out of my twitter account after using it, freaks me out.
  • (2020-12-16) Yarrow: This doesn't work, and it locks my browser and computer up to the point where I need to restart. This extension said that I had successfully blocked about 60,000 accounts, but when I ran an audit on my account, it has blocked fewer than 4,000.
  • (2020-12-15) ConquerWithin: as of 12/15/2020 has not worked
  • (2020-12-14) Thewaterspirit57: Doesn't work at all. the export and import bits don't do what they're supposed to and so-and-so I'm trying to chain block their followers of blocked me fix it :V
  • (2020-12-09) Mason Abunda: This app is garbage. I tried blocking an account and all of their 6k followers and I only blocked about 1-2k and I can't log into Twitter on chrome anymore because of this apps uselessness. If you don't want to use Twitter on chrome this is the app for you.
  • (2020-11-27) little bitvh: I lost my twitter account after using this.
  • (2020-11-25) Yunaa: Worked but I was a little scared at first bc it disconnected me of my acc and I couldn't do anything at all :(. after that I realized that I needed to log out of all my accs, reconnect and change my password and it worked again! And all the people I wanted to block were blocked! thank god it worked ;-;
  • (2020-11-21) Esteban de la Maza Guajardo: I used this extension a lot before twitter's last big update months ago (the one that changed it's looks) and I never had a problem with it, but now with the new twitter it doesn't work at all, something about the interface doesn't let it run. Would it be possible to fix that? This extension was great and I'd love to be able to use it again.
  • (2020-11-21) Sam: Almost always run in to errors using this. Full list doesn't get blocked, it crashes my twitter and force logs me out, and then eventually I can't even open Twitter without an error and I have to uninstall the extension.
