Search engine land has a story of an advertiser who was hit with the ban hammer for advertising a service that provides information of where traffic speeding cameras are located. As a result of the ban, the company had to let 12 people go. The French regulator said "Google had abused its dominant position in the internet advertising market when it barred a location data company from using its AdWords service".
This is very interesting because I've heard a lot of talk about anti trust in here from people who have been banned. As far as I understand it this is not a judicial ruling, but it might set a precedent for future regulations.
Maybe with this in mind, now would be a good time for those who feel they have been unjustly banned, or that Google abused their power, to file anti trust complaints.
I understand why Google is doing what they're doing, but since they don't seem too worried about false positives, or providing banned advertisers with proper means to dispute a ban, I have to agree that Google abuses its dominant position and I support any efforts to call them out on it...killing someones business overnight without explanation isn't cool, and the case in France is a good example of how it affects many more people than just the person responsible for keeping up with the TOS.
