The way out? Well you are allowed to share the Links to the various types of Contests on your Google+ Brand / Business Pages. This is ofcourse while you clearly mention that Google is in no way a part or responsible about the contests, sweepstakes, offers, coupons or other such promotions that you may share.
Note: Google holds the right to remove your Promotion Content from Google+ Page for any reason.
Play safe: As long as you have clearly mentioned that Google and all of its group is not responsible for your contests, sweepstakes, offers, coupons or other such promotions, and that you / your company is solely responsible for the entire contests, sweepstakes, offers, coupons or other such promotions then you perhaps are a little safe.
If anyone Flags your Page then again you can stand a chance of Google taking action.
There are Five audiences that can flag you and get you banned:
- Google has one of the greatest algorithms which can easily recognize your Content and can with ease know that you are going against their rules
- By Community Members of your Page
- By your Personal Profile Page Network
- By Other Pages where you join and may spam
- By Members of the other Pages where you have joined and are spamming
Bottom line is that Google+ / Google should not be involved directly or indirectly in whatever you do. It is your liability. Simply put if there is winner involved, if there is give away monetary non-monetary then you need to follow the rules tightly. Promotions that are leading people to take action on your or their Google+ Page calls for Google to cut you out.
