Sorry, but if a program changes their linking code, it only makes sense to grandfather the old codes. I've got sponsor content from dozens of sites used as upsells in paysites, AVS, free sites etc. Changing them all everytime a model decides to jump ship isn't practical if the link was hard coded.
Ivy put up free content given to affiliates. She posted the banner & link that was correct at the time. If anybody is getting screwed here, isn't it Ivy? Her members are now being sent where? Your 404?
For the people complaining about upsells in the members area...ya'll should really try joining some of the paysites you promote. How do you think they're paying $35 on a $2.95 trial???
