Hey, I'm not
allowed to say this is a fantastically dumb idea in proper journalism, am I? This was lesson I learnt on my first day working at a magazine. My initial assignment was to attend ANSI C++ standards committee meeting. I went along, carefully collected up all the drunken gossip, came back, and wrote up how incredibly doomed I thought it looked. My editor pointed out that yes, it was doomed, but some of my audience didn't think that, and they'd be the ones who'd really like to know what went on there without all this editorialising, thank you very much. This is not to say that I agree with that, which is why we ended up doing
NTK. Some things are just too stupid not to pass comment.
Aaaanyway. Habeas is basically MAPS on a stronger legal footing. But do blackhole lists work? Dunno. You're suspicious about them, because they seem very manually-entered, very arbitrary, very prone-to-corruption, and very anti-connectivity. But there's a whole bunch of people - sysadmins mainly - who love 'em. All of your criticisms work, I think, for any blackhole system, not just Habeas, so it's a bit harsh to say that these are all flaws exclusively of their system.
I think Habeas' problem is less that their plan completely sucks, and more that the one group who really applaud the idea of blackholes will be suspicious of clever legal hacks. I spoke to a few sysadmins yesterday, and they were very "Hmmm. Neat. Yeah, that sounds okay.". It was interesting to wake up and watch the slashdot hive-mind turn against it.
