This item was created in the format of Japanese road signs. Please feel free to use it when you want to ask someone to report when they see a Kiriban. I would be delighted if you could place it in your world. "Kiriban" is a cultural phenomenon that became popular on the Japanese internet in the 2000s. It celebrates visitors to a website when the visitor count reaches milestone numbers like 1000 or 2000. Back then, it was frowned upon to overlook this and leave without acknowledging it.
Japanese road signs are in the public domain.
