"We here at YLB are dedicated to the task of preventing you from getting fired because of social media. While common sense goes a long way in properly using social media, a little advice never hurts," the post reads.

Handy Twitter tips include "Do not tweet about your lack of motivation" and "Do not tout recent job offers", while Facebook users are helpfully advised "Do not use Facebook to bash your job, your colleagues, your boss, your company, or your clients" and "Assume everyone can see everything - don't lie to your boss about a family emergency, then post a picture of you dressed as a fairy at a Halloween costume party time-stamped on the date of the supposed emergency".

This job sucks worse than the economy!", and "Having sex dreams of people you work with makes for an awkward day."
