I think PayDotCom.com has a script error.
A few days ago I watched a friend of mine enter random names like dave, kim, makingmoney, etc as usernames in a PDC link code. Here is what happened. After the link redirected to the site it had the code in it for, with the name mike, kim, or whatever that affiliate got imported into his PDC acct as a real person so that he could email them and ask for their promotion of his new site. He ended up with tons of new affiliates since PDC has over 20 million registered affiliates with them.
