A crowdsourced Chrome extension filters spam-like web articles.

Amid the recent proliferation of apparent low-quality articles, content farm websites such as Demand Media, Seed, and Associated Content, among others, are soon meeting their end. After gathering insights about content farms from Internet users, Google has recently launched an extension that blocks these sites from appearing in search results. From the Google Blog:

We’ve been exploring different algorithms to detect content farms, which are sites with shallow or low-quality content. One of the signals we’re exploring is explicit feedback from users. To that end, today we’re launching an early, experimental Chrome extension so people can block sites from their web search results. If installed, the extension also sends blocked site information to Google, and we will study the resulting feedback and explore using it as a potential ranking signal for our search results.
