Slightly related, Google+ had a requirement for using your real name. I of course didn't want to, I was using 'Jason Gutentug' and they banned me, but after getting about 40-60 people to say it was my real name, they accepted it.
Point being, even if they require real names, trust me, people will always find a way to trick the system.
@INIT6 @HRandbusiness @pluralistic Google Plus had so much potential. I remember starting to use it immediately because it was finally a place that did what Facebook did, without the real name requirement. I like being Zorin the Lynx on the Internet. I don't want to be my real life identity there socially.
Then of course they ruined it by demanding people use "real names”, which caused near everyone to leave after their friends started getting banned. The bans were badly implemented, disabling your entire Google account instead of just Plus. Even I left myself.
They must have realize they f-ed up, because they removed the policy, but by then the damage was done, it never came back to what it was and they killed it.
Bad decisions are part of Google culture I suppose.
