Why was my AdMob account disabled?
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.
As you may know, Google treats invalid click activity very seriously, analyzing all clicks and impressions to determine whether they fit a pattern of use that may artificially drive up an advertiser's costs or a publisher's earnings. If we determine that an AdSense account may pose a risk to our Google Ads advertisers, we may disable that account to protect our advertisers' interests.
As outlined in our Terms and Conditions, Google will use its sole discretion when determining instances of invalid click activity.
If you previously participated in AdSense and your account was disabled for invalid click activity, you cannot participate in the AdMob program.
