More blacklist discussions

A good article in The Washington Post about blacklists and their implications.

As I've stated before, II think that they're fine, but that the users need to pay attention to who is making them and what their motives are.

The alternative is not (as the spammers how) having no blacklists, it is having white lists, which will be much more cumbersome for users and much more effective at rooting out the problem.
