'I just hope this type of culture doesn't goes to Pillowfort or here in Dreamwidth'

I'm far, far less optimistic, for a number of reasons. One, a ton of anti and anti-adjacent people might not come to DW specifically (on account of it being an older platform and lacking things such as easy harassment means) but I've run into quite a lot of them on PF so far and my guess is more of them will go there / to other platforms, as Tumblr continues to shoot itself in the knees (remember that the algorithm is flagging almost everything imaginable as NSFW -- quite a few of those censorship-cheering idiots had their own 'pure' content nuked).

Secondly, fandom antis aren't a singular phenomenon. Knee-jerking about 'gross' content is something that's happening right now even on game-modding communities on Reddit, if you can believe it! Purity culture and all its associated nonsense (people utterly forgetting that 'no victim = no crime' is a thing, for example) is on the rise almost everywhere -- fandom is merely one of many smaller microcosms reflecting society's neuroses.
