I would probably pick a different intermediary for this... Google + pages are still fairly new, and I'm not sure how forgiving Google will be about "spam" to a Google+ page... Think in terms of there not being a way to request a reconsideration on your Google+ profile page. At the recent PubCon in New Orleans, I believe Charlie Ellis talked about how the patent for agent rank included language on trust being easily lost and difficult to regain.
If you are getting great user traffic from your forum signature links, I might consider no-indexed landing pages... this way you get the benefit of the traffic, but maybe not the full risk of the links.
