hi mousie,
i'm sorry I stopped checking rs awhile ago. without knowing your username i really couldn't say - if you felt comfortable leaving it in another anon message, on neospring probably, or DMing from your other account I could maybe give you specifics.
i block people if they don't have their age in their bio i have missed this before when it's in a spot I don't expect.
i also block people that post stuff that i don't want to see on my tl. this isn't even necessarily I think it's bad, I just don't want to see it. if we really haven't ever interacted then the likelihood is someone else was reposting your stuff and it contained something I, personally, didn't like.
I will also block people if I see them talking about/using ai.
i have also made mistakes before and accidentally blocked people i really liked, so i can't really know without your @ sorry.
i don't think it's weird to want to know, especially with how the block system works now, but ultimately i will block people to keep my peace and i think everyone should do the same. but like i said i am willing to talk to you about it more specifically if you want.
