I've seen ridiculously hostile and inappropriate comments posted with full name and photo (using the Facebook comment system).
As a particularly dramatic example, which was so bad it was almost art, we had a debate in a Norwegian newspaper about what to do with the traveling Romani people who put up their tents everywhere. One commenter said: "Why not put Anders Behring Breivik on the case? He cleaned up a camping site in an hour", referring to the Utøya massacre where 69 camping teenagers were killed.
If someone's able to post that with their full name and photo, I don't really think there's any hope of solving the comment problem without old-fashioned moderation.
I would have initially read that comment as a sardonic remark on the European conception of Romani as needing to be "cleaned up," but I'm not aware of all the cultural issues.
Social norms are different in different groups. I have told people that what they wrote could be considered racists and gotten a reply back that they wanted to be clear that they were racists, quite proud of it, and that I was an idiot for not seeing the muslim thread (in a discussion that was not at all related to terror). I have seen the same people belate others for questioning that we should throw all muslims out and arguing that every single muslim was a terrorist ala The Norwegian terrorist.
