mastodon.art has decided to suspend firefish.social from their instance due to issues with its administrator. The administrator of firefish.social was found to be boosting posts from a known harasser on another instance. mastodon.art takes a firm stance against racism and suspending full instances in these situations is part of their policy as a safe space. The known harasser has a history of using slurs, harassment, and editing screenshots to spread misinformation. However, the administrator of firefish.social has now forged a screenshot to paint mastodon.art in a negative light.
The iceshrimp fork actually came before the thing with .art broke and seemingly had to do with issues internal to the calckey development community. It’s hard to say for sure what the situation was because most of the stuff on both sides was pretty vaguely stated.
