That said,I feel that Google AdSense also has a responsibility to protect those of us that place an ad to make not only us, but Google money. Termination, suspension, and disabling accounts shouldn't be done upon a mere suspicion. Granted, I don't know the internal process that goes on at Google Adsense, but I suspect that the "investigation" isn't so much of an investigation as it is some computer program sending up a red flag when any ad gets hit multiple times by the same PC. If so, this isn't suffice evidence to just disable a user's account and refund any/all earnings. After all, any writer can attest that readers will and have stooped to some pretty low blows when they disagree with the content of an article or blog post. I've seen threats, insults, name-calling, and pure word rage from simple subjects like coupons. I know I know that reader sabotage isn't always just online threats that never reach your real life; sometimes, those irate readers can cause you a world of trouble in real life.
