My AdSense just got disabled because apparently it “poses a risk of generating invalid activity.” Now I am assuming this invalid activity is referring to invalid click activity. I have never clicked on my own ads, I have never encouraged clicks on websites that the ads were placed on, I have read and made sure to follow the policies set by Google, and I have never received any warnings or notifications about invalid activity happening with my AdSense account.

According to the Disabled Account FAQ, Google refuses to tell you the invalid click activity they have detected since, “Because we have a need to protect our proprietary detection system, we’re unable to provide our publishers with any information about their account activity, including any web pages, users, or third-party services that may have been involved.”

Furthermore, the only way to contact them is by their appeal form. You only have one shot at the appeal and if they deny the appeal, they will not look at any further appeals and you are pretty much permanently banned from AdSense since they will not let you open another account.

I am now presented with this when I login to AdSense. I can no longer view any of my reports or any of my account information on file.

This was the email I received about my account being disabled. It does not specifically explain what the invalid activity is or what invalid activity they have detected.

This message was sent from a notification-only email address that does not
accept incoming email. Please do not reply to this message.

Hello,

After reviewing our records, we've determined that your AdSense account
poses a risk of generating invalid activity. Because we have a
responsibility to protect our AdWords advertisers from inflated costs due
to invalid activity, we've found it necessary to disable your AdSense
account. Your outstanding balance and Google's share of the revenue will
both be fully refunded back to the affected advertisers.

Please understand that we need to take such steps to maintain the
effectiveness of Google's advertising system, particularly the
advertiser-publisher relationship. We understand the inconvenience that
this may cause you, and we thank you in advance for your understanding and
cooperation.

If you have any questions or concerns about the actions we've taken, how
you can appeal this decision, or invalid activity in general, you can find
more information by visiting

Sincerely,

The Google AdSense Team
