use the Flag button on article's like this. If you see articles getting upvotes, and you read the article and think "this is a crappy, poorly written article and a waste of all of our time", Flag it.
From the guidelines:
"If you think a story is spam or off-topic, flag it by clicking on its "flag" link. (Not all users will see this; there is a karma threshold.)"
"Off-Topic: Most stories about politics, or crime, or sports, unless they're evidence of some interesting new phenomenon. Videos of pratfalls or disasters, or cute animal pictures. If they'd cover it on TV news, it's probably off-topic."
