My account has not been disabled and I am a happy AdSense publisher. In fact, I have nothing to #*$!-and-moan about. Simply love Google (PR department, please send the check to ...).
However while checking out competitors websites something occured to me. Google tracks our IPs to prevent clicking own ads (I don't know why people would do that, but apparetnly there are plenty of fools around). As a publisher, I never click my own ads, but I do tend to click quite a lot of ads by my competitors (well, not by, but rather ads displayed on competing or related sites), while doing research. When something catches my eye, I'll click and ad and see what's it all about. I'd imaging that my competitors may do that too.
If this happens quite regularly (which isn't really case for me, because I can abandon Net for weeks at the time), I'd think that this would look to google like a classic click ring, right? I click ads on site A (competitor) regularly while seeing what my competitor is up to, and owner of site A clicks ads on my site, because he is competing head-to-head with me and wants to see what I do. Any thoughts if this could be behind
"I got disabled, but I swear I never clicked my own ad" posts? Especially if it's a niche with 5-6 websites where everybody knows each other.
