This is somewhat irrelevant. Google says in the TOS to not do that, but they don't ban on that alone. What you get banned for is based on data. Everytime they ban someone, they want enough evidence, so if it ever went to court, they don't look foolish. You can have no effect, or even some when asking people to click. You have to break thresholds to actually get banned. And even if there were some users egregiously 'supporting' the site, the people can overlook that and just deduct from the account. To get automatically banned means you broke some nasty thresholds.
