Mark Zuckerberg, the founder and CEO of Facebook, says they are working to improve Facebook's ability to weed out these stories. In the meantime, some creative people have come up with solutions of their own.
A number of browser extensions exist and while they don't work 100% of the time, they can help users by flagging suspicious or untrustworthy sources. Some examples include
