Wouldn't a publisher be protected from this tactic by using the "Allowed Sites" feature?
Finally someone with a valid point. I withdraw what I said earlier about such "tactic" but I am still stuck to what I am saying regarding the mass ban because of saturation, or lack of adsense support employees.
Again, in the old days on each incident concerning your account you used to get a human notification. Worst case scenario you would be getting your infringing site/domain banned (and announced) if against the TOS.
I never was banned before so I can't comment on how "appealing requests" were handled, but I know now that they are ignored. Officially they say it should take up to 48 hours but might be taking "days". Mine is two months old (not that I complain as I am over adsense already) and others are "months" old.
Just checking on the official adsense forums will amuse some of you with the horror stories there.
