I've had my Adsense for Content account for just over 9 years as of now. But last night, it was disabled without any sort of warning for non-compliance with program policies.

This account in its entire lifetime has ALWAYS been in good standing with Google. It has NEVER been suspended or even received a warning for violating policies or invalid traffic.

What's odd is that 2 hours after the account was disabled, the payment for last month's earnings were still issued even though the account was already disabled.

I personally checked all of my sites and everything seems to be compliant from what I can see. I was never given a warning so I never had a chance to resolve whatever violation google found before the account was disabled.

Any ideas about this? Could it be an error on Google's part? Any input on how I could get it back? I submitted an appeal but not sure if that will go anywhere.

I've searched tirelessly on the internet and have not found anything similar to what happened with my account. Either people have gotten warnings before getting disabled, suspended, or they were disabled without warning for invalid traffic. I would think for an account being established and in good standing for so long I would at least get warning or get suspended for 30 days.
