We've been getting a lot of SPAM in the last couple of weeks, mainly it would appear from Russia, at least the text looks Russian. If you look at the memberlist you'll notice a lot of new users in the same period. They will be banned in due course.
But if any should slip through simply ignore them, don't even bother to tell them to p**s off...they will be deleted.
For some reason this seems to happen only at this time of year...
