I've read a bit about people hijacking query strings and inserting their own Id to get commission on affiliate programs. How prevalent is this? How do they do it? How easy is it for someone to do this? How can I protect my commissions w/o getting banned the PPC people? Thanks!
for PPC is harder unless they are using spyware/adware such as some toolbar who just converts the ids people talk that zango is doing such things but I don't know for sure, I didnt debug their soft and there is not much you can do to prevent it..
