Isn't this yet another manfiestation of the same old troll problem the internet has had since about, well AOL?
- Advogato tries to get around it with a trust metric system.
- Slashdot has both moderation and meta-moderation.
- K5 has a more open voting system.
- On USENET, you get either no moderation or central moderation through a single address (but with a set of moderators or a bot). But this is usually fairly slow (human) or not very discriminating (bot).
None of these get rid of trolling completely. The closer you get to troll-free, the more stringent the hoops one has to jump through to participate.
So, although I'd like to see the ideal voting system, I don't really know what that is. Anyone have any ideas to help the situation rather than just finding one or two fools who are abusing it now?
After all, there will always be fools, and you can't keep them away from the site anyway.
