I am also seeing strange numbers since the per email promotion ended.
If the payout had simply dropped from $2.50 to 0.50 I would expect my RPC to drop by 80% also, with same traffic.
However it has dropped by 85-90%.
So I am missing 5-10%
BUT this is pay per profile not per email, so where are all the people who didn't confirm their email or it got spam filtered out?
The wording on the signup page hasn't changed.
It still says you need a valid email to join.
So if 70% of people aren't confirming their email now, the same amount weren't confirming it before and I would expect a 70% increase in free members in the current pay per profile deal which would equate (it's late I may be wrong) to only about a 33% drop in RPC
example: 100 free joins
during $2.50 per email I would expect
100 x .3 x 2.50 = $75
during $0.50 per profile I would expect
100 x 0.50 = $50
So I am expecting a 33% drop but get an 85-90% drop
Is my math wrong?
