Seems to me if their only concern was malicious or maligning posts, they could verify signups as planned and still let people use a screen name. That would address the concerns of both posters and readers. The fact that they want real names and cities, even after verifying accounts tells me they are after a bit more control of what's being posted.

Also, imho, anyone that can't get past an ignorant post until it is removed (or even if it isn't!) is a thin-skinned control freak.
