Weird name person sending me a message.

So a user with a weird name with random letters and numbers has just sent me a message saying that only mods can see the msg and if i can see it there is a security problem or something. He also said that the message was automated. I looked the user and he had just joined, so probably its just a troll. Since i didnt see a report button, i post this just so that you do something. He has just sent me the message once, but it seems like he made the account just for trolling.
