The 'Pornhub Alternatives' meme revolves around the instantly recognizable black, white, and orange branding of the internet's most famous adult site. By applying this specific visual identity to mainstream platforms like GitHub, YouTube, or even LinkedIn, the meme creates a humorous juxtaposition between professional tools and adult entertainment. It originally gained traction as a way for developers to joke about their obsession with code repositories, often referred to as 'Dev Porn,' but quickly expanded to include any platform that users spend an 'unhealthy' amount of time on. Today, it serves as a popular visual shorthand for internet addiction, UI design similarities, and niche community humor.
