We've been experiencing an elevated amount of automated account registrations that, in addition to posting to SPAM to topics, have also been sending SPAM via private messages, so you may have received a notification that you've received a new PM only to find no new message in your inbox. This occurs because the bad accounts are often deleted before you visit the site to read your new PM, so you can simply ignore it when it occurs.
Although it is not possible to completely stop them, we have taken additional steps to minimize these automated registrations.
