I'm hoping someone may have some ideas on how I can handle this problem?
My client is offering a paid online subscription and after the person pays via clickbank, they are redirected to the registration page. This works fine for most part, however I have some people that have discovered the link to the registration page and keep registering "free" and hence getting members access. I have to then unregister them and delete their user account.
The system must be automated so I cannot manually approve the registration.
Any ideas how I can handle this issue?
