If an instance doesn't want a negative reputation for doing certain things, they should prioritize not doing those certain things.

If you act like an arse, people are going to think that you're an arse. If you want people to think that you're pleasant, you should try acting pleasant. If someone acts like an arse but expects to be called pleasant, I would think that person is delusional. Too many people are like this, then get upset when people don't want to deal with them.

Frankly, life is too short to deal with certain people. Why would I waste my time and happiness for a troll?

I might block the instance soon. It doesn't seem like I would be losing much at the moment.
