I will be releasing the code here and on my site is a day or two. It is writen in php and uses MySQL. It has a logger the admin can get to and read. The ability to set status's for account holders.

Currently status's are

In good standing
Under investigation
On Probation

Still left to build

Ban by site URL, email, and IP

Automatic set to investigation if site takes burst of hits within an hour. (Smart Logging)

Cookie setting to help keep cheating down.

a Viewer rating system which will have to do with the ranking of sites.

If you have a site please sign up I need users to help test functions. If you want a copy of this I will post a copy of it here that will require very little editing on your part.
