Ad space has gatekeepers. This doesn't. bid4head is a public auction for space on people's faces: list your forehead, drop ad spots on it, set your price, and anyone can bid on them. A bid is a photo, a link and some vibes - your mum, your mate's dead YouTube channel, MrBeast, all in the same auction. Highest bid wears the crown until someone outbids them, and 80% credits the forehead owner's wallet.
