invalid clicks problem

someone wants to get me out of adsense

[noha_alas21]

i've noticed more than usual clicks on my feed ads through email subscriptions with a great revenue
these clicks are generated by one subscriber and i dont know his email or any other data about him i just know his city using adsense reports because there is no way to get enough data about subscribers that click on ads through email and i think this is a smart way to close someone`s account i have sent email to adsense and explained this problem but he still click on all ads in each email he receive from my feed subscription ... dont know what to do >> i know i can reject all my email subscribers but i don't want to loss that source of revenue and he can register again to my feed subscription and repeat that again ..so please help me

is there any way to stop that or to track clicks through emails ?

Just another reason I opt out of this type of adwords abuse.

Take the adsense ads out of the feed maybe.

Yep, that's what I did. Never made enough to make it worth losing an account over anyway.

Could you a-b test to find the culprit.
You know, split the list in 2, give half adsense and the other half some affiliate offer. (Doesn't matter that it may not earn, its only temporary and there to make sure the punters can't scream 'but this used to be ad free!')
Do the clicks stop? He's in the affiliate offer group. Do the clicks continue? He's in the adsense group.
Take the group he's in, resplit and repeat (the other group goes back to adsense)

That should find him!
