The 'Kira Hudson's Facebook Lesson' meme originated in early 2014 when a mother from Colorado posted a photo of her daughter holding a sign intended to show how quickly a photo can travel across the internet. The original goal was a lesson in digital privacy, but the plan backfired when users on 4chan and other image boards intercepted the photo and began photoshopping the text on the sign with humorous, absurd, or satirical messages. It became a legendary example of the 'Streisand Effect,' where an attempt to warn against internet behavior leads to the exact behavior happening at an accelerated scale. Today, it is used to mock the naivety of social media users or to spread custom messages through the iconic white sign.
