The Threads 666 logo conspiracy theory emerged almost immediately after Meta launched its Twitter competitor in July 2023. Internet users began circulating images suggesting that the 'at' symbol-inspired logo was actually a stylized triple-six, often associated with the 'Mark of the Beast' in popular culture. While Meta designers clarified that the loop was based on a continuous line representing the flow of conversation and inspired by the Tamil letter 'ma', the meme took off as a way to satirize corporate overreach or indulge in playful tech-based paranoia. Today, the meme is frequently used to mock deep-dive conspiracy theorists or to express distrust in social media conglomerates through a humorous, occult lens.
