When making a thumbnail, a bot has to check the game first, if the thumbnail is NOT the same with the game... (Example) Like making just an obby and the thumbnail was call of duty, ROBLOX deletes the thumbnail.
Solution: If x amount of people report the game for false thumbnail, then a mod can check it. If it seems to be nothing to do with the game, they can delete it.
Solved!
How about thumbs up/down on them, and if it gets more than a 75% of the plays of down delete and and 1 day ban for the owner. And if this happens 5-6 times remove the game with 1 week ban.
"You would need a bot with artificial intelligence."
We are not in Halo, where we got tons of bots everywhere, you know how much one, JUST ONE of those AI online bots or whatever that's called costs? Well, a truckload of cash.
