@Felthry this is so, so relatable.

@Felthry some people just react to any interaction with blocking. it's their own aversion to people that causes it, not your actions and you don't have to fix your behavior of it.
Y'all didn't do any thing wrong. I know it's easier said than done, but it's ok to not take the blame for this.

@curls i just, don't knwo what we could have done wrong? the only interaction we've had with this person is one or two times we said something positive about their art
-F

@Felthry it could be any of a million things. It could be they misinterpreted you, it could be that for some reason they don't like people posting comments on their pictures. It can also be they have some arbitrary prejudice or something.
But you are right to feel confused because they didn't bother even telling you why, and it's not up to you to figure out why they act like that.

@curls @Felthry This. There's no guessing what that person is going through. They may have misunderstood something; they may have made an outright mistake. They might be someone who had offended you in the past, or thought they had, or mistook you for someone they had, and feared your wrath.

It hurts and is confusing but does not mean you've done anything wrong. I'm sorry you have to deal with the results of it.
