I have never understood the concept of trying to make yourself look good, by making others look bad. With social media this makes this even worse. Keyboard warriors, internet trolls and standard haters can pretty much post anything they want regardless of the consequences.
The only problem with this is that some people take that information as factual, with no evidence or supporting documentation. A good example of this was the 'April Fools Joke' on Facebook that stated you needed a third ORV sticker to ride your ORV in Lake County. As it was not meant to be a scientific experiment, it definitely proved the point of how misinformation is so easily spread across social media.
