Fake Mark Zuckerberg Facebook Posts, also known as Zuck Memes, refer to screenshots of Facebook Co-Founder & CEO Mark Zuckerberg's public Facebook posts which have been digitally altered, often making him appear as a tyrannical megalomaniac, robot or reptilian humanoid pretending to be human.
According to The Washington Post, rumors the Zuckerberg was planning a potential campaign for the presidency of the United States began in December 2016 when he began a year-long tour of each state in the nation. On February 20th, 2017, Zuckerberg posted a photograph of himself reading a newspaper with his wife outside of the Selma Times-Journal in Alabama, along with a story about visiting "local newspapers" as they drove through the state. That day, Twitter user @PixelatedBoat tweeted a photoshopped version of the post in which Zuckerberg discusses forcing an elderly man to eat a newspaper, which gathered more than 19,100 likes and 7,200 retweets over the next seven months.
On May 1st, 2017, Twitter user @edzitron posted a photograph of Zuckerberg feeding a calf milk, captioned with the fake quote "Beef of the past. I am Zuckerberg. Drink of this beef milk I have grabbed from the sustenance teats. Soon you shall be burgers. Glorious" (shown below, left). That day, Twitter user Mark Constantine posted the same cow milking photograph along with the caption "Hello I'm Mark Zuckerberg and I enjoy providing nutrients to the protein units on my free time like a regular person" (shown below, right).
Also on May 1st, The Next Web published an article titled "Mark Zuckerberg tried doing 'everyday normal' stuff, the internet trolled hard," highlighting examples of people mocking Zuckerberg's Facebook posts. On September 27th, Redditor markrtoon submitted a post titled "Zuck memes horribly undervalued" to /r/MemeEconomy, along with a photoshopped screenshot of a fake Zuckerberg post in which he refers to himself as a "tyrannical god-king" (shown below). Within 24 hours, the post received upwards of 13,700 points (93% upvoted) and 130 comments.
That day, /r/zuckmemes was launched on Reddit for photoshopped Zuckerberg Facebook posts. Within 20 hours, the subreddit gained over 6,700 subscribers. On September 28th, Redditor astroaron submitted a post asking "Why is Mark Zuckerberg a meme all of the sudden" to /r/OutOfTheLoop, to which Redditor Creshal responded that it was due to his "awkward Facebook posts" that resemble someone planning a "political campaign."
