Well this newbie will add this.

Keep your ads off the content networks. Everyone is trying to make money off adSense. It seems like we get a lot of reliable valid traffic just on SERPS ads. There is nothing to be gained by clicking on a Google serp ad for the fraudsters, other than trying to bring us down by attacking our budget.

Real world case of "oops my bad" - I set up adSense for a former employer. When he expressed concerns, "how do I know if it's a competitor?" I explained the methods for determining this. I then implored, vehemently, don't click your ads. Use your adSense login. Don't click your ads. And once again, if you are thinking of clicking your ads, don't.

Two days folks. They were banned in two days because he just couldn't resist, it seemed so much easier to just ease his curiosity by clicking his ads than to log into his account and use the penalty-free way. So Google does try, but as usual - no barriers for the truly motivated.
