These are inadequate options. The issue isn't whether you like to see them on News.YC, it's do you want to start banning people. Yes, I don't like seeing them on YC. But no, I don't want to ban them.
Come on! Isn't this a democratic news site front page is voted on by readers!?! This vote is absurd.
I think a better idea would be to institute negative points to submissions, not just comments. That way, the handful of people needed to make news frontpage worthy can be rejected by the masses tired of Valleywag.
If you have to ban sources on your democratic news site, you're missing the point.
