Read the answer from TryNinja, someone just teases you and wants to scare you, there is no real danger in the sense that someone can hack your account.
I know, I am not retarded.
If you know, why are you still insisting that someone try to hack you in a way that is impossible to hack someone's account? The fact is that you have angered someone and that person is trying to get revenge on you, but you don't need to pay too much attention to it. The best way would be if you ignored the whole thing or reported it to the admin via PM.
I have some good advice for you, choose one of the two semifinals Croatia plays today, open a beer and enjoy
