I'm trying a mix of CMS on a variety of names, and my biggest problem at the moment is spammers. Surfer interaction sectrions include guest books, forums, comments, image hosting, URL shortening, classified sales, and e-commerce sites. I've set registration to requiring admin approval following email confirmation, but I'm still ending up with pages of applications. It can take ages to delete them all if the CMS doesn't have a bulk deletion facility. I'm thinking of implementing two methods of combating this. - redirecting all Russian traffic to a Russian landing site - is there a way to monetise this? - having a central membership site, and adding members to various sites by hand, or maybe allowing logins for all sites based on the "club" membership. Has anybody else solved this problem? email spam is another problem, but I'm just black holing all of the domain emails.
