Anonymous didn't release a list of names, it released a list of pseudonyms which is virtually useless (http://pastebin.com/88Lzs1XR). I presume these people are smart enough not to use the same pseudonym on other services so this list is pretty eminently useless.

Actually, I just did a cursory google search on a few of the more unique looking names, and they come up all over the internet. One of them is definitely not too worried, their pseudonym is also registered on a bestiality/zoophilia forum as well as some overclocking forums. I think this is definitely enough information to nail some of these people, with the right investigation.

No guarantees though, choosing an existing handle/username with a tarnished reputation seems like a pretty good strategy to me for online shenanigans.

What if they put your name on the list? To what authority is Anonymous culpable, and what responsibility do they have to vet the names they release?

Well, clearly, in the anarcho-capitalist utopia envisioned by ryandickherber, you would go to the private justice authorities of your choice and get a ruling in your favor by presenting evidence that you never download child porn. An empty hard drive, say, or the entire server logs for every website you've ever visited. Easy! ;)

More seriously, you hit on the problem, which is that a lot of people seem to be assuming that Anonymous' vigilante justice is error free. Those that are wrongfully accused of using child porn could have their lives seriously damaged.

"Communities" can't do that as effectively as the government can nor are or should these people considered to be guilty unless proven in court.
