There was a list of subreddits, which participated in 12 VII blackout. I tried to make list of equivalents of these on Fediverse - to make switch to Lemmy/kbin easier.
Thank you for the answer! There is one lemmy community which is listed there that I am a mod of, and the fact that a search with its name isnt making it show up on tchncs.de lemmy instance made me question whether something was wrong lol. Glad to know this was a thing of the past! And of course, thank you for the effort in making this list! :)
