alien, moonbitcoin, .. all reduce average satoshi
So far I have not to reduce because i have not google adsense.
but if my referrer incomes decrease I have to do it.
But it can also be possible that more people come to my systems because they pay more...
To be honest...I have seen so much cheat against adsense that I was astonished that adsense accept so many insentive clicks and anti-rules displaying.(not for BonusBitcoin who has just been limit with displaying...not with insentive clicks)
The problem with adsense is as well the insentive display...
Even if you put a adsense banner on a page after a login...you can be taken for a cheater...
if people (referer generate to much insentive trafic you can have problems...
pages from rotators as well...it is horrible if you read the adsense rules...
adsense can cancel your account for 1000 things...and you have only the eyes to cry...
