I have never done any illegal sort of things on Google+. Therefore never experienced the misfortune of getting banned.
No, I don't have this sort of experience yet. I have never violated any of their rules yet I believe.
Yes, for some reason like name violation or posting spam SEO links on your page Google may ban your Google+ profile.
I am one of the person, whose G+ account was suspended. I was new to G+ account and using G+ for SEO, but i have never read guidelines or something else regarding G+, I was adding more friends in a day..I think that was the reason i was suspended from G+.....
Yes, i banned by google plus because i tried to +1 and share everything that i posted on my wall. And dont know the reason why. Google banned my google plus account for 1 month. Now, I am free.
It's happen if we don't work such as in natural way or do violation of rule than should be banned for any social sites or website please keep work in boundary Thanks!!!
