This is a long post, but if you use clickbank, you need to read it. I found this article about affiliate theft.
Most clickbank vendors are honest because they value their affiliates. But, there a few clickbank vendors that use these sneaky techniques to steal affiliate commissions:
Hijacking visitors
List building. Squeeze page is good mailing list generator, but in clickbank affiliate program, it is misused. For those who don't know, a visitor must signup and only then he is forwarded to sales page. What this means for you, affiliate? No signup, no possible commission. With signup, email of YOUR visitor is collected, and it is used for selling other products too. This is possible only on ClickBank - Free Lead. On other affiliate networks, they have to pay to affiliate for Lead too.
Anyway, percentage of affiliate sales (%refd) could be indication what vendor is doing with his mailing list. Signup, and check. If you are receiving newsletter with affiliate links (redirections), test that link. If that redirection contains your nickname, you can promote that product, your cookie will be set again every time when reader clicks on link in newsletter. If there is link to vendor's site only (clean url), that is nice too, but cookie could be deleted or overwritten in meantime. If there is some link to other product, that is really not nice.
(fyi: you can check to see if the vendor is doing this by signing up for his newsletter under your own affiliate link and then clicking on a link in the newsletter to see if it uses your link to go back to his site or not.)
Commission hijacking
It is well known that some affiliates and vendors are using spyware to steal affiliate commission. But some vendors are using old tricks to steal affiliate commission on their site. Today, when ClickBank Marketplace is updated daily, their position is going down (no affiliate sales), so it is easy to spot when is something wrong with that vendor. Below are some examples of commission stealing.
