ANOTHER IDEA

Not that you may really care where you a user directs traffic to your site FROM, but to ensure they are not placing tags ANYWHERE, I am considereing additional security over and aboe the 10 digit security code, to include Referrer checking agains the URL in you database.

Example: The counter is on a site www.xyz.com. If this matches the url in your database when an IN click is received, it will increment the IN counter. If there is no match, the jump will still occurr, but no IN will be recorded!

I am just wondering how many honest sites this would not work for if $ENV{'HTTP_REFERER'} did not pick up their address properly?

Just another idea, comments welcome.
