Problems with Google Adsence clicks and earnings

Some really strange things happen with my Google Adsence clicks. It happens that click appears on Google Adsence report, it shows both clicks and earnings, but in 10 or 5 minutes it reduces both of them.
As I noticed it happens usually with the clicks from my home page... and the click rate for this page is really low...
I checked all recommendations about putting ads on the page, everything seems according to the rules.


It'is happening for few weeks (probably from 1st of May)


Please help and share your ideas, what could be done wrong?

First of all they scam and secondly, when they don't scam, they only count click through's, not just clicks.
