Unfortunately over the weekend we've seen quite a bit of spambot activity, particularly concerning visitor messaging, although they seem limited to only a few members - we ban them as soon as we find them, but it still seems that they manage to fire off these nonsensical messages before we do.
Sorry for the inconvenience this might cause, but I'd suggest that if anyone else is having the same problem it might be worth disabling visitor messages as well until we can stem the problem.
