stop forum spam catches a lot on the site i am admin on during registration.
it also catches a lot on the site i am staff on.
he gets a lot more traffic than i do.
I've got a handful of plugins from Ozzy/Painbreaker and Xon installed. I get 1000 new registrations a month, usually one spammer sneaks thru and a couple scammers find their way in, the balance are handled with the plugins. There IS still some Admin work in the Approval Que every day for those that trigger the "moderate" settings.
