I would think that if any advertisers in France are dealing with similar issues
I've been looking, for about 20 minutes there on the Francophone web, using a variety of search terms equivalent to "adwords closed my account" etc ..and can find only 3 cases of people complaining tht adwords shut their accounts.
One guy in Morocco who was running arbitrage to his blog ( ran adsense on it used adwords and facebook to bring traffic ) and linking to adult videos.
And one in metro ( mainland France ) ..again running adwords / adsense arbritrage ) ..and who admitted to clicking on the adsense ads.*
And a french guy in Greece again running arbitrage and who admitted to clicking on adsense ads on his site "to test them"*..
Apart from those three, all I can find in French language refers to the NavX case, ( as in just reports about it )..or is translations of cases in the USA..
Of course my search was not exhaustive ...and there are others here from France ..maybe someone else has heard ..bear in mind that France has no equivalent of WebmasterWorld ..and no dedicated webmaster forums as such, that are not part of other sites as sub fora ..
I also searched in Google's own support fora in French and only the two cases marked* showed up ..( doesn't mean there are not more ..doesn't mean there are ) ..but I didn't see any more.
Maybe outside of the English speaking world and/or in particular the USA, it just isn't happening or is not a problem ?
As I don't use adwords I woudn't know .. I read the threads and have commented in the past on QS ( which strikes me as "smoke and mirrors"..paying more to run your ad can improve the quality score ;-) )..but had not heard of this particular circumstance until you posted.
