If it ever were the case that Google would lock you out entirely, that is no longer the policy (nor has it been for a long time). A lot of the early reports that people were getting locked out of Google were centered around one person, who claimed to have been locked out from Google over his name, but it turned out the lockout was because he'd uploaded questionable images to his account (I can't find a link at the moment, but here is Matt Cutts alluding to it: https://plus.sandbox.google.com/u/1/+MattCutts/posts/NNJduMF...).
:\ you are joking right! did you read the policy? i'll quote "If your profile is suspended, you will not be able to make full use of Google services that require an active profile such as Google+, Reader and Picasa. This will not prevent you from using other Google services, like Gmail. Your profile can be restored by editing your name and submitting an appeal that will be reviewed by our team, as directed by on-screen instructions."
soooo nothing has changed! if they dont like your name or if you dont have a good enough proof bye bye!!! im not spreading misinformation, my coment is still pretty much valid, there is still to this day a chance that by signing up to Google+ that they will suspend your account!
The policy, for the record, is here (see the bottom of the page): http://support.google.com/plus/bin/answer.py?hl=en&answe...
