What do I do know? This person is being rude.

Oh I've run into that guy. Ignore him, he's like that to 90% of people. He went at this other user (who is one of the sweetest people on this site) for a poll on the animals club. He tried to have a go at me as well so I looked through his comments and half of them are provocative.

Just report him for abuse, and ignore. That user is most likely just doing this just to get a reaction from you.

Just report and ignore. It's pointless to concern yourself with that user.

I'm sure it's just some immature eight y/o who's completely bored with his life. I've never made contact with this user but I have had experiences with people just like him and I don't take it too much to heart. I'm pretty sure you should be able to flag/report this users account. If he keeps bugging you— tell me and I'll hunt him down and karate kick him in the face (no, I'm jk XD) If he keeps bugging you can always just click the 'Block User' button at the bottom of the message.

Block him, maybe. But that only works when it comes to inboxing and wall posts.

Oh, look, he's still alive. Hasn't messaged me much since I blocked him. ✌
Yeah, he's a nonsense speaking troll who tries way too hard to sound poetic. Just block him.
