I was just checking the announcements (altcoins) board (after a long time) and a user caught my eye. This is the account: Unikon

He made several announcements of major projects. I don't know if he's actually the official representative of those projects, but it's unlikely. What I'm worried about is that if someday people start paying less attention to this user, he will change the OP by inserting malicious links. What's more, all threads are set to self-moderated (as most scammers behave). So far, there is no self-disclaimer that confirms the identity behind this account and its role and rights.

Are there any rules for this case?
