An anonymous reader writes, "Over the past few days, adult webmasters have been accusing adware maker Zango of 'stealing sales' by means of the following method: Computer users with Zango's adware on board will pop open a window containing the affiliate merchant's site they happen to be on at the time, except with Zango's own affiliate code in the window. By doing this, Zango claims credit for the sale and the original, rule-following merchant, the one who referred the user there, loses out. Despite this practice having been around since at least 2004, it seems the adult webmasters are only just realizing this takes place — surprising, considering how deeply connected the worlds of adware and porn are. It seems pornographers pushing adware is acceptable only as long as they aren't the ones getting burnt. Part of me doesn't care, and part of me hopes they carry the financial clout to force Zango to change their current practices."
