This probably explains why you never hear of lawsuits against Google for unjustified adwords ban.
If you did no evil; Google will reverse the ban for life.
Otherwise a court case would go like this.
Judge: Why was the plaintiff banned from Google
Google: It's our policy not to discuss why advertisers were banned.
Judge: I find for the plaintiff, reinstate the advertiser and pay all damages from lost of revenue.
Rinse and Repeat: until you get to the supreme court
