(Sending off-anon intentionally)
In case the link doesn't work, this ask is regarding the anon asking for advice regarding their past in a small fandom with a toxic friend group.
I wanted to try n help since I was in a similar situation. I also used to be part of a small fandom and befriended/became mutuals with a large chunk of the people in it. These people also used to harass bigger artists for being 'proship' (I say it like that because they didn't label themselves as such they were just lumped in with proshippers). While among those 'friends' I'd spread/make callouts or talk shit about certain artists.
It's probably been 2-3 (?) years since all that happened and since then I've cut myself off from those people completely. I'm just barely getting back into making fanart for this fandom.
When it comes to apologising to these people; that's up to you. If you feel it's appropriate you can try to reach out. Personally, I only managed to apologise to one person. They were kind enough to accept my apology. Not everyone is gonna react like that ofc. But you'll find people are generally more understanding than you think. Though when in doubt, just leave them be.
I also recommend blocking. Block a bunch of people in the fandom. I've blocked every ex-friend/mutual and anyone associated with them.
It's entirely possible people won't even remember that you were involved with your ex-friends. It's been 3 years since 2023. That's a pretty decent chunk of time.
Wallowing in your own guilt won't change anything. I know it's not easy cuz again, I was in a similar situation. I still feel guilty for my past actions and I still have people I want to reach out and apologise to. The best thing you can do is start somewhere.
I wish I could give better advice but I don't know the specifics of your situation. I don't know how involved you were with these artists or if you were on a different platform like I was (I dunno but this situation seemed reminiscent of Twitter fandom stuff.)
But yeah. Regardless I wish you the best and believe in you ^w^
