It's a well-known fact that unsourced, unverifiable, anonymous Tumblr posts are an agent of social progress and meaningful change. So it's surprising that some prick used "Racists Getting Fired," an enormously popular new web attraction, to smear his ex.

A full-on Internet manhunt is currently underway for a young man who callously assaulted a street performer in broad daylight, and then uploaded footage of the attack to his Facebook page.

A woman who had her phone stolen while vacationing in Ibiza was given an excellent opportunity to name and shame her victim, but then went and kinda spoiled it by being sorta racist.

A gym rat in the most literal sense of the term found himself banned from an entire chain of gyms thanks to Internet vigilantes who decided to punish him for mocking members on his Facebook page.

An earnest, yet ultimately toothless last-ditch effort to save Lindsey Stone from termination proved no match for the thousands clamoring for her head.

While visiting Arlington National Cemetery last month, Lindsey Stone thought it would be amusing to snap a photo of herself "disrespecting" the Tomb of the Unknown Soldier by flipping it off and pretending to make noise.
