I have funny but first a quick history lesson
In Ancient Athens they had things called ostracons. Basically every year everyone would carve a name of someone they didn't like into a small stone tablet and then submit it. Then they would look at all of the ostracons and if there were too many of one person then they told that person to get tf out. They had ten days to flee Athens and couldn't come back for ten years.
So now I would like you to imagine Dionysus doing a pseudo version of this at Camp Half-blood every month because we all know he LIVES for the drama. (He's stuck there for a hundred years he might as well have some fun)
He would hand out stone tablets (it was very important to him that the names were carved don't ask why) and every person at camp would write a name.
Whoever had their name written down the most would be sent to live in a cabin in the woods for two weeks. If they survived they would be allowed to return to camp.
Mr. D always makes sure there's a crowd around to witness their walk of shame and he takes a picture of said person every month. He keeps them hung up on a wall in the big house.
