for example if some one want to band me from google adsense and click many time in my ads . dose google band that IP ganesh
I don't think Google will ban you, but they could ban that ip address. But if this continues for long, es they may ban you.
that's correct, for example if someone is clicking on your ads 5-7 time's a week this is't big problem but if someone from the same ip click every day 10-20 time's then google may ban you
If someone is clicking your ads over and over again, then Google will think that you are paying someone to click your ads and they'll disable your account.
This is not possibe. Google will never ban the IP of the person who clicks your ads. In the same time google will not ban you either. So they will never pay you for the clicks, but take care of the people who clicks your ad and that is not a good sign.
But how can we "take care" of our enemies who want to get cancelled our adsense account?? Is there any idea??
Google wont ban the IP but instead it will warn you through mails stating that random clicks are being made from this and this IP and will advice you to block them promptly, if you fail to do so your account will be suspended
Thats very good to know. It's a good way to block out enemies that really do malicious techniques to get us banned.
