I had a friend of PATH come in and do a change to the security of sign-ups on the boards. It uses logic questions instead of using images to challenge people when they sign up. That should protect us from a lot of the bot sign-ups we've been plagued with. Effective immediately, please do not immediately ban someone when they sign up. Give them time to authenticate their account and make a post that we can verify is spam before banning them.
If you have any questions, please contact me via PM or email.
