Forum Spam Control:
This is a subject that all admins are faced with on a daily basis and is a major pain for admins to deal with, who can join the forum and who can't stay are based mostly on what the members post i.e. content which all members are responsible for, and admins and moderators are always watching, we have adopted a new policy of screening new memership with a anti-spam network which is very effective at eliminating possible spammers before they are even alllowed to post, ALL new members are screened before being approved as a member on this forum for any spam notices from a data base that collects and shares this data. Admin
This is one of the sites we use to check all new accounts for any complaints or reports of spam.
