Google has abolished the "real name" requirement for Google account.

This might mean that Google+ is acceptable to use. But I am not certain, because I don't know the answer to two follow-on questions:

• What other personal data must one supply to make an account, and do they amount to identification of the user? Is it possible to make a Google account named "Rumplestiltskin358", contacting the server through Tor, and not enable Google to identify you?
• Does that require running nonfree Javascript code.

Later: Google+ is useless without nonfree Javascript code, so it should not be used.
