Unidan, the pseudonym of biologist Ben Eisenkop, was once Reddit's most popular user, known for his enthusiastic wildlife facts. His downfall began in 2014 during a pedantic argument over whether a jackdaw should be classified as a crow, which spawned the famous 'Here's the thing' copypasta. The controversy peaked when it was discovered he was using 'sockpuppet' accounts to manipulate votes and silence critics, leading to a site-wide ban. Today, the Unidan meme represents the peak of internet pedantry, the fragility of online fame, and the hilarious intensity of niche scientific debates on social media.
