Agreed, not just because someone is being an asshole. Everyone should feel the need to protect their personal information, because the world is full of assholes of different levels and your personal information being publicly available can only cause harm to you. It really is as simple as setting your profile to “friends only” to counter the lowest level of assholes.
11 of those comms are on ani.social, an anime-centric instance where it is totally legit to split “pictures of anime girls” into more specific comms. It’s not unhinged or spam at all, but if you don’t want to see anime, probably best to block ani.social tbh.
I for one like to see all the moe on top of my local feed and not pushed down to page 5 of global.
