It takes, iirc, 500 karma to be able to flag an article. So it would take 5 users with 500 karma each to knock it off. It'd take a lot more effort than it was

It takes, iirc, 500 karma to be able to flag an article. So it would take 5 users with 500 karma each to knock it off. It'd take a lot more effort than it was worth for a sockpuppeteer to do it, but I bet any company with 25+ employees could knock an article off the front page if they caught it early enough, and were able to marshall enough people to do it.
