Previously, I was a publisher of google adsense, but some one targeted me (dont know cause of competition or jealously) and violently clicked on ads for continuously 1 week, and atlast after my every effort, my account was disabled by google. Offcourse they have predicted suspicious activity in my account, but this is also true that I was not responsible for that. Hence I have a suggestion to protect both advertizers and publishers from such attacks which currently google dont provide.

My suggestion is,
 


   If we allow the publisher himself to decide whether the click is valid or not. This can be done by providing the publisher a option in control panel, where he/she can monitor all the clicks, and if he finds the clicks to be invalid , in the control panel itself, he can deny those clicks. There wont be violation to  privacy policy, as you won't need to show the ip addresses of clickers, instead whole thing can be tabulated in form ::

Address 1 :  10:15am
Address 1 : 5:10 pm
Address 2 : 10:20 am
Address 3 : 4:55 pm
 (here the ip who clicked on 10:15 am, has again clicked on 5:10pm ,so that publisher can deny the accepting second click)
so on..

(here no ip add. will be shown to publisher, only a symbol for one ip address.

Hence by doing so, all the repeated clicks from a single ip can be monitored by the publisher himself, and he can deny all such clicks. Hence the publisher will be surely remain safe from invalid clicks and your team will not need to monitor all the accounts,instead only those account who still find invalid clicks in their earning zone.

Please suggest your reviews on what if publishers are equipped with such feature.
