I got a report on one of my posts, It was for the mods of lemmy.ml letting them know that porn was popping up on .ml. I went and checked lemmy.ml's instances and we are now in the blocked list. I know they had a number of large communities so this is just a heads up to everyone who may have been subbed to any.
Yea, the ability for individual users to block instances as a whole is really needed to stop this from becoming a thing that just happens frequently. Strength is definitely still in federation and people are going to get annoyed with having to have multiple accounts because their instances keep defederating from each other.
