Emily Bazelon generalizes that online anonymity is 'poisoning civil discourse' with 'largely vile and defamatory comments' (trolls) & thinks identify should be linked to comments. Others feel this inhibits free speech. Pick a side:
How does linking your name to comments inhibit free speech?...
It may not be the real name. I could see a lot of identity theft in requiring your real ID on a comment page.
1. Don't divulge personal info on the internet
2. Ignore/avoid trolls.
I today's Information Age ignoring trollers isn't always an option. I recently received death threats, to my cell phone and stating the name of my lover and my address, from a troll because of positive comment regarding LGBT folks in another ...
... forum. I had to get the police involved, and the Fed authorities since it's online and between states. Being anonymous doesn't help free speech, it sets up a environment where there are no consequences for what you choose to say.
I don't think that would be necessary.
Or here's another solution: ignore trolls and stop being so sensitive to what a random username said to you. That's a novel idea.
