Yes I was thinking of getting a vBulletin license but I'm strapped for cash right now coming up to Christmas. As for admin approval I could but it's not a permanent solution, If I start to get more traffic it's going to be hard to upkeep all the new members. I really want to know who has the time to get through all my security features and activate their account just to post some advertisement about shavers and handbags...

It gets me thinking though, are there any key words spam bots are attracted to or is it just site activity.
