Guest posts in admin only forum?

Woke up to find numerous guest posts which obviously passed through my security. I deleted them all, however I'm stumped. How was the bot able to post in my admin only account as guest?

Sorry, my mistake. I have a deletion rule set up to send deleted posts to my admin forum. Sorry about that, I tried to delete this but don't have perms.
