I hate being forced to use my real name online. I can think of only two sites/applications where I do and that's because it's directly related to my work.
The Google push for real names was partly (apparently) because of the ridiculous nature of comments on youtube, but humans are amazing and it turns out that having your real name next a racist, homophobic or just outright dumb words doesn't actually stop people racist, homophobic and dumb.
Why not just enter a dummy name? Or make a new gmail account with a dummy name?
