It's not hating, it's just this general reaction against strangers even seeing your posts.

I haven't actually been subject to this, yet, but I've seen enough people react negatively against others doing this that it saps all my desire to do anything other than just aimlessly scroll every once in a while. I can read the room, you know.

Sometimes I wonder why do instance admins even open up their instances? Just run it for your friends and those who you like and cut the crap.
