I'm Danelaw.
He also claims that Danelaw is Warsong's brother and is using his runehordes account. None of us can either prove or disprove that statement.
You do know what the alternative would be... and how the horde listing would look like (again) then, right?
Yeah, I know. Which is why I'm careful to point out that the only person with any sort of "right" to be bothered by this is you. You could, however, limit horde registration to people who have accounts on this forum. Meaning that when one registers a new horde, one also leaves behind a name, an IP and an email address. That way, most of the abuse would be taken care of, and you'd have a whole lot less work to do.
