It's generally difficult to have it done by a computer (ie auto-registration and post) due to the image verification. Also, this forum is set up to not allow users to have multiple user names per e-mail address, and thus need multiple e-mail addresses in order to get a new name. This makes it difficult, but not impossible, to have a computer handle registration and spamming. However, our moderators have been doing a good job of deleting threads and banning users. If anyone sees a spam thread, please report it to that forum's moderator or Zaphod, so the thread can be deleted and the individual banned. The 2011 candidate is probably just an automatic selection. Unfortunately, these types of spam attacks happen on every forum to which I've ever belonged, and they are basically unavoidable.
