Hacked Affiliate Link

Hello Warriors

Although I visit this forum on a daily basis and very seldom make any posts, I know that I will receive the answer that I am looking for here, where I have learnt a heck of a lot so far.

One of my blogs that I am using to promote some affiliate products has been hacked, pretty cleverly as well.

When I follow one of my clickable affiliate images on my own computer all the way through the product's squeeze page through to payment then my clickbank affil. name shows at the bottom of the page as per normal

Now, it's a spot on sales page and should convert very well, I noticed that I had only had one conversion this month and it didn't seem right.

My plan of action was to go into an internet today and go to my site and follow the same link through to payment, and wo behold there was a different affiliate name where mine should be

Back home an hour later I repeated the process on my machine again, have a guess - my affiliate name was there.:confused:

Obviously the hacking software or whatever knows what to show on different ip addresses

Now I do not know whether it is a random hack, or is it perhaps the product owner switching the links???

Any advice and a course of action to take will be greatly appreciated.

Thanks
Mike
