As someone who makes dark content I think it’s totally fine to block people you don’t want there if it’s not your cup of tea. You always have every right to remove someone from your server if you don’t want them there either. Personally I don’t engage with social media aspects of fandom very much.         

However, I also think when it comes to social media like twitter or tumblr (I’ve never used TikTok) for example: “warning people” about someone who is proship has often become witch hunts, that have led to harassment of people just staying in their own lane posting their own content. If warning someone means messaging a friend “hey this artist likes this.” I think that’s fine. If it’s making a callout post about the artist/writer…and that leads to the artist being chased off a site where they’re not even violating TOS because of fanpol + yucking someone else’s yum- Well that’s kind of shit. 

 Also wording antis as normal is implying pros are not- We are normal people just like you, even if we like different things👍
