The built in script protection has a secunia vulnerability posted against it 
stating there is a method to circumvent it. You can find it here:
http://secunia.com/advisories/23281/

Simply checking the domain submitting is the referral etc is not always fool 
proof as we've found individuals on certain proxies get bounced everytime as 
performing invalid actions when they were not.

The solution we came up with was salting a hash based on certain key pieces of 
information that come from the (authenticated) user with some randomization 
added, and putting that as a hidden in all forms. If the hash doesn't match up 
we bounce em before the form processing occurs.
