Why did you start a new thread for this question? Keep it all in one thread it'll help people give you better answers.
See OP, this is why you don't start a new thread. Browning doesn't know the situation so he thinks you're doing something dodgy.
Yeah, in an earlier thread he posted about how a friend of his is mad at him and is threatening to click-bomb his ads to get him banned. So the OP is trying to figure out how he can save his account.
ah I've this type of thread here before. Personally I wouldn't worry about. If you are, relay the message to adsense so you'll have a little backup if the friend decides to show what a pud he really is and go forth with it. If you know or can get the ip of said friend send it along with the email to google. edit-I apologize for assuming you were up to no good
Yeah, I noticed that thread too.. Well, Theres no limit IMO. If the clicks are legitimate, them may be 4 or 5.
There must be certain limit but the number of clicks shall be less than that for a particular IP so as not to arouse suspicion for the google; but never try to check what is the limit!
