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 phiếu bầu on the động vật club. He tried to have a go at me as well so I looked through his các bình luận and half of them are provocative.
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 bạn 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 bạn can always just click the 'Block User' button at the bottom of the message.
