The Taylor Swift 4chan conspiracy theory originated in late 2011 on the imageboard's /b/ and /v/ boards, where users began noticing strange coincidences between anonymous posts and Swift's real-life actions. Key evidence cited by believers includes an anonymous poster asking for name suggestions for a new cat just before Swift named hers Meredith, and threads where a user claimed to be a celebrity spending their night on the forums. The theory gained massive traction as users cross-referenced Swift's clothing and public statements with specific forum 'get' requests. Today, the meme is a staple of deep internet lore, used to poke fun at the intersection of celebrity culture and the chaotic anonymity of imageboard history.
