Google can disable your AdSense account if it detects suspicious clicking activity on your ads, even if it doesn't come from your own IP or, indeed, your own country. This is to prevent people from clicking on their own ads or asking other people to click on them. But what happens if a competitor starts clicking on your ads all the time so that Google picks up suspicious activity and bans you from AdSense? Can this happen, or are there safeguards to prevent this? If there are no safeguards, what's the best thing you can do to protect yourself against click-bombing?
