Over the years, we’ve seen dozens, perhaps hundreds of prominent examples of social media posts from the past coming back to haunt someone. It’s bad when it’s someone else who posted an image that got someone fired or otherwise personally damaged. It’s worse when the individual posts something stupid on their own.
A very easy example to latch onto is the story of Lutz Bachmann, former leader of Germany’s Pegida protest movement. They have been mostly considered a fringe hate group until the terror incidents in Paris fueled their anti-Muslim protests and made their ranks swell. Right when they were on the verge of getting the type of following that would make them powerful, their witless leader was found to have posted a selfie as Adolf Hitler.
