- (2025-05-23) Katherine Rose Martinez: Helpful but could use more customization. I like the concept and it’s caught a few things already. Just wish I could adjust the alerts a bit more or whitelist certain sites.
- (2025-05-23) Ben Richardson: Does what it says. Flags fakes. I trust it.
- (2025-05-23) robust solutionagency: Caught a fake PayPal scam before I clicked I’m 35, work in IT, and even I almost fell for a fake PayPal text message last week that sent me to a fake site. The site looked identical, but NotCommon flagged it. Saved me from entering my login on a spoofed page. Super clean extension, just works.
- (2025-05-23) David Harrison: Helped me spot a fake account spreading lies Saw this account on X posting some wild stuff about a news story, and it was getting tons of traction. Looked pretty real with decent profile pic, thousands of followers. But NotCommon flagged it right away. Said the account was only a week old, no linked sources, weird bio inconsistencies.
- (2025-05-23) Bertram Langley: Saved me from a fake store that looked so real
- (2025-05-23) David Adebowale: not gonna lie i didn’t think i needed this but it’s actually fire. like i’ll be on insta or tiktok and get a sketch link in dms and this thing just straight up lets me know if it’s sus or not. green dot = chill, no dot = nah bro. super easy, doesn’t bug you or anything. def recommend if ur tired of all the fake spam stuff everywhere.
- (2025-05-23) Marcus Alderton: I’m 72 and I do most of my banking, shopping, and chatting with my grandkids online now. Sometimes it’s hard to tell what’s real anymore. My daughter helped me install this NotCommon thing and I’m really glad she did. Now I see a green mark when something is safe, and if it’s missing, I know to stop and check. It’s simple enough for me to use and makes me feel just a bit more sure of myself when I’m on the computer.
- (2025-05-22) Lucy: Last month, I got an email from someone claiming to be a vintage synth seller I follow. The site looked right, even had the same logo. I was this close to wiring a deposit. But the NotCommon icon was not green. Sure enough, the domain had been registered like three days ago. Total fake.
- (2025-05-22) Jennifer: I’m usually the last person to install some new browser thingie. Half the time it just slows everything down or nags you with popups. But NotCommon’s different. It’s weirdly calming. Like, I’ll be scrolling through someone’s profile and see that little green light and just… breathe. Doesn’t pretend to fix the whole internet, just helps you not get burned. And that’s enough for me.
- (2025-05-22) Beatrix Lovelace: As someone who works in research, I’m constantly digging through links and online profiles. NotCommon has become a useful layer of protection, especially on social platforms where it’s not always obvious who’s behind an account. I like that it consolidates metadata like account age, profile info, and links in one place. It’s not intrusive, and it’s already flagged a few sites I probably would’ve skimmed past without a second thought. Definitely recommend for anyone who takes digital trust seriously.
- (2025-05-22) Marcus Roderick: Honestly this extension gives me peace of mind. With so many fake accounts and scam links out there, it’s been super helpful to just see the little green check and know something’s verified. It works in the background and doesn’t get in the way, but when I do click it, I get useful info about the site or profile. If you’re tired of wondering what’s real online, this is worth installing.
