I didn't refer to absolute anonymity, but to an anonymous design (anybody can register, without an email even). The point is that it's far easier for INS to troll a place with real identities like Facebook. I don't think the NSA's resources are about to be spent on determining the commenter's Vietnamese parents' identities. If parent were threatening a mass shooting, that would be another story. But as they say, technically correct is the best kind of correct, so kudos.
