Just a guess, but it is likely 90-99% of
Azoogle users have signed up under someone else's id. That could mean 1.5-2% of their incoming revenue is written off immediately. If they are already operating on slim margins this could be a 10%+ boost in net income.
Presuming that
Azoogle's profile is high enough that any big affiliate will find out about them, the cost/benefit to continuing a good referral program may be minimal, especially in the short term. (long term I think they may be in serious trouble.)
