comes off till I nail them down.
When I stopped following that I recall that it still wasn't nailed down, just seemed to fade away on it's own. So, at what point if you can identify something but not stop it do you add AdSense back? Would you really leave AdSense off forever if you couldn't stop whatever Bot was hitting your site? Seems like if you could identify it Goggle could as well so their Traffic Quality Team would just subtract those clicks/views. I suspect that's what happened in HuskyPup's case.
