My adsense account just got disabled for invalid clicks, I have never ever clicked on my own ads or broken any of the TOS for that matter. I got click bombed last week and reported the suspicious activity to google almost immediately. I've just submitted an appeal, and google says that I will have to wait a week or more before I get a result.
This whole thing has really shaken me up as I rely on my adsense as a significant part of my income and I have always been soooo careful to follow googles TOS to a t.
Anyway thought I would share this as it seems that click bombing is still alive and working. I will get back to yous with what google's out come is.
It will be interesting to see if google really protects their publishers from these kind of attacks.
