I've added an anti-bot question to the registration page, which makes you answer the question Which company made the SP-404? which bots don't know but hopefully all real people do. (they can always Google it of course).
If you see any new spam posts in the future be sure to hit the Report button in the post, it's the little icon with the exclamation mark found in the top right corner of every post.
Thanks to the people who already did this
