I have a forum and I place 300x250 adsense ads in each topic. I want to ask if an user click my ads for 2 or 3 times in a month, for example, because he/she is interest in that ads do google ban my account for this clicks? Thank you.
If he/she is interested on the ads from your website, why could you be ban for that. If you encounter click bomb, report his ip to Google first! No fear!
Asking anyone to click on your adsense is against Google's TOS and yes you WILL get banned. Once banned from Google's adsense program it is extremely unlikely you will ever be accepted again!
Yes i now if I ask someone to click on my ads is against google adsense TOS but I ask you if the user are interested in the ads and maybe they will be see some interesting ads and click on it.
Yes, they can ban you for that. So advise them not to click. If you have to ask this question, then it is against the policies. Otherwise, you would not ask because you would not know. But since you are aware that a user may be doing this, chances are it is not in the user's interest.
If u dont want risk then dont show ads to users when logged in. Show ads only to visitors like visitors comming from search engines or other trusted sites but dont show to members U'll loose some $ but not ur adsense account
