Yep. I've seen them shit up other peoples threads with hostility at the OP like that, I decided not to block because they hadn't done it to me and I didn't know the history.

Never interacted before and they just went off on me, made up my mind.

If they are seeing this post it really seems like they need a friend or some human connection. They won't get it from me now. Treating others that way will only make that connection harder to find.
