I dunno lol. These are all the reasons I've blocked accounts that I remember
-You repeatedly repost people's fanart without crediting them / pass it off as your own
-You repost composites I've made efforts to put together without credit
-You take news I've taken pains to uncover and repost it as if you discovered it
-You've been very rude (cussing people out, pushing your fetishes on others etc)
-I ask you to stop doing something and you keep on doing it and are rude when I ask again
-You keep making off-topic replies and having conversations on my posts but don't even follow me
-You have "Paw Patrol" in your name but your account is actually nothing to do with PAW Patrol but still shows up in searches I do a lot
-You wrote that one of the professional artists' works I reposted looked like "disgusting AI" or something. But this person apologized and I would unblock them if I could remember what their username is! (Feel free to write it on Formspring if you see this.)
I see blocking not as a great insult or anything, but as a mute button that actually works. I understand perfectly well that unless I lock my account, people can still read my posts / steal things / take news to repost elsewhere. So if I've blocked you, it's not that I think your behavior will be changed by what I did or that my blocking you is a super big deal; it's just that I don't wanna see your posts any more and feel like my life is a bit comfier without seeing what you're writing or having you reply to what I post.
