Ok guys, question for you... I'm running a script with a squeeze page. After you send a link on the page, unique to you, to 15 different people, it reveals a banner which leads to another page from where you can order a free sample of a product. The issue is, some people, (yes I know stupid of me) - figured out the link to go straight to the product ordering page, where you get the product for free. they circulated that link around the internet, so now people don't go through my squeeze page. What do you guys think I should do to prevent this?
