I went ahead and got a Google+ account - under my pseudonym! I won't use my legal name there, period.
I have used this pseudonym for 30 years, and there are people IRL who do not know my real "legal" name. If Google+ wants to ban me, fine. I've been around since before they were, and I'll be around when they are gone.
I have more links on pseudonyms for your perusal, of course:
