There was no TOS violation, just an algorithm gone wild.
This happens to me all the time but with Google adwords
- Google Adwords tells me not to run more then one domain in an ad group then suspends the ad group... that has only one ad in it. Takes a week for Google to undo their suspension.
- Google Adwords suspends an ad, support says that during the signup process there should be a page that links to competitors with a comparison of prices as features. Sort of like going to a K-Mart but once your at the checkout the checker says "you shudda gone to Wal-Mart sucker!" (to save a dollar). Takes a week for Google to undo their suspension.
etc and so on. If you spend 20k a month or more with Google adwords when Google wants to give you pain they find very unusual ways to do it I presume to mess with your click history to force you to pay more, so Google quarterly profits go up. I presume this happens throughout Google's products.
