I've noticed a number of new users that have cropped up in the last month that are visiting high numbers of other users' profiles. These new users have no posts, all have similar features in their profile (long ICQ number, "Man" for biography (even if the username and profile picture are female

), and all have external websites in their profile.
One of them linked to the Google search results for something called XRumer, which appears to be some sort of "forum promotion tool".
I worry that the registrations of all of these users may be a sign of a mass spam attack to come. I've only got a couple of usernames, as initially I thought nothing of it. But admins/mods, feel free to PM me and I'll be happy to share those usernames that I do have.
Cheers ^
