Over the short holiday break, we were hit with almost 50 posted spams (which already made it thru a captcha, form validation and email validation)! So we made some more changes today, which seem to be stemming the massive tide of spam we've been getting. We've removed the captcha, which seems to be worthless anyways and have instead been using a simple form question and answer field. So unless the spam bots have gotten good at figuring out what a planet is, or what type of animal my pet is, this should take care of the spam. Of course, we said that last time too, so who knows.
However, we've had this system in place for about half of the day today, and have had zero spam registrations (and one valid registration). That's a far cry from the dozens of fake registrations we were getting a day (we deleted almost 600 fake accounts for the last 3 months alone).
If anyone runs into any problems with the new registration system, please send Mike or I an email so we can resolve the problem.
