As long as you don't contact them there is plausible deniability on google's side that their programmatic measures/bots missed the stuff that a lot of people are complaining about. Google can play dumb and still make money. Once you contact them about it you've taken the plausible deniability card away from them.
But I still have to wonder if it was the shady tactics/pitches you were using or if it was strictly because of the offers that they booted you.
Never ever under no condition contact google there is absolutely no reason they arent your friend and will never help you with running ads or increasing your quality score. Its a totally waste of fucking time dealing with google. And you always at risk of violating there TOS. They are the Soup Nazi you talk back or ask stupid questions they will say "No Soup for You!!!"
