Jim,
These are actually robots that are beating the anti-robot registration that I currently have in place for the forum here. They are designed to put up as many links to websites as possible, and, as we all know, are really annoying. This anti-robot registration had worked for about 7-8 months without fail, but recently we have been hit pretty hard. I appreciate it when you guys report them as SPAM and I usually can get the posts removed in a short period of time as long as I have internet access. I am currently working on setting up another anti-bot registration for the forum and hopefully, when put into action, it will limit the amount of these posts.
Best regards,
Chris
