My sports site, which had published AdSense ads for the last few months, got the dreaded 'deactivated due to invalid clicks' email a few days ago........no warning, just deactivated.
We're a free site...and it's well known on the web that publishers like us rely on revenue generated from clicks on such banners. We have NEVER incentivized those banners, NEVER breathed a word to our members that clicks help us out, and even requested Google to check our site out completely to see if any potential violations existed.
We got a clean bill of health at that time. And now, suddenly, deativated with no further explanation than that they considered some of our clicks to be invalid.
How can we correct a behavior when we don't know what it is?
What can we do to get our account reactivated?
I also find it interesting that we're deactivated just prior to the time they're due to cut us a check.
