Let me turn this around. I don’t think Itch should tell you who is following you. Blocking a follower should be a complete non-issue because you shouldn’t know who your followers are in the first place.
I follow people because I want to be notified when they release or update projects. That’s it. I don’t do it to boost their egos or as an invitation to some kind of two-sided parasocial relationship. Telling the person I am following that I am following them feels like a violation of my privacy. And I am not violating their privacy because following them shouldn’t give me any information that isn’t already public.
(Technically following does give you access to information that only followers get in the form of game reviews, but that’s just another misfeature that I hate about Itch.)
Also:
I agree, if you block you have to block everything, it happened to me yesterday to block someone who after just one minute of registering on the site came to follow me, it seemed suspicious to me and I immediately blocked him,But I keep seeing it in the people who follow me, even if I’d like to delete it I can’t.
Sorry, what’s suspicious about that situation? Person comes to Itch and hangs out for some time. After browsing for some time, person wants to follow someone. Person realizes that they need an account to follow someone, so they create an account and hit the follow button immediately afterwards. If you think that’s suspicious, then maybe Itch should allow you to opt out of being followed at all.
