Hi there, well there are some offers that dont allow EMAIL, i want to ask why? How can they know if the leads are from mails? how to cloak if they know? Maybe with a domain? thanks
They know via they HTTP referrer that's passed through. It's possible to "fake" the HTTP referrer however, a dude called Brad1001 or something similar used to have a kick-ass application (wordpress plug-in and stand-alone version) that did this. Just run a a search on this forum for his name and I'm sure you'll find it.
