There are a lot of other linkbait articles that float up to the front page. The "businesshackers" guy comes to mind. There have also been a number of completely vapid articles recently, such as the "to be a programmer, you need these 10 things: 1. text editor..." article. I can only hope these are linkbait for some SEO scam network; the thought that these articles are written and upmodded by actual hackers is too depressing.
Anyway, at least we know Valleywag is a "real" site which sometimes has humor or interesting gossip. The other linkbait sites that make it to the front page truly have nothing to offer. The current moderation scheme deals with Valleywag just fine. If you must ban, there are other sites which seem to be a higher priority.
