Block a comma separated list of bloggers
Tumblr Batch Block lets you block multiple users at once, without the hassle of having to block them one at a time.
With this extension you can mitigate the damage of a harassment campaign by stopping the hate mail, potentially before it even starts.

amazing for blocking nazis, terfs, aphobes and other awful people <3
Works exceptionally well! Typically very quick but it can be a while if the list is super long, though it's much faster than doing it by hand!
works really well, I blocked like 10000 terfs (via the disrespect-terf-juice blog) and it took a bit of waiting and letting it run in another tab, but worked great!
No longer appears to work following the recent tumblr update.
Hey, thank you so much for making this. I was able to copy my block list from main over to my sideblogs. It was pretty easy to figure out!
Keeps giving me errors like "You already blocked this user" and then won't continue...
It worked great for me. You can go to this website -> https://convert.town/column-to-comma-separated-list <- to change block lists to lists separated by commas instead of doing it yourself. I disabled this extension after blocking everyone (50+ blogs) that was on the list. Thank you so much for making this extension!
