I made guests able to post and it fucked up and spam got on the boards as I didn't tick the capacha for guests postings instead I unticked it from the registration page... DOH
Of course, spambots came in (They weren't listed on StopForumSpam though)
Spam bots made new topics and also replied to a few triggering a few emails
I made a backup but yeah
I reconsidered this decision and guests cannot post topics or reply to topics after this but they were able to for a few days...
