Just for future reference, please report this kind of thing directly to one of the mods or admins (I know you can directly report a post, not sure offhand about doing it with PM but I think you can?). I deleted the link you posted for obvious reasons, and we'll look into this user (check IP address, etc.).

If anyone else got this kind of PM from this (or any) user, please let us know privately so we can take action. Thanks.
