I have had dozens of friends suspended from Google+.
Some were using their real names and thought it was insane that they'd have to send a scan of their driver's license to some stranger at Google in order to prove they were who they said they were. So when Google told them to show it or leave, they left.
Some I have known for years on other social networks by the name they were using here, but they couldn't prove to Google that it was a name they were commonly known by, so they were ejected.
Some I know offline, by their pseudonym, or only by their first name (maybe real, maybe not, I don't know or care) and they also had no way to prove that their name was their common identity, and for reasons of family, work or community; for reasons of persecution, harassment or discrimination, they could not safely use their legal names online, so they too were suspended.
And some I met here on Google+, and had friendly and educational discussions with before Google decided that they hurt the image of this social
network and threw them out.
All of them are gone. Many wouldn't come back even if Google allowed them…they no longer trust Google with their personal data.
