Does this mean Roblox is preventing the 40% method with the classic pumpkin head? Last time I saw this message was with headless horseman

Assuming it's not a glitch, the idea of pricing something over 2000 robux more than what it was for 10 years straight and then preventing a method that gets less than half of that robux back has to be some of the greediest shit ever thought of by anyone. Also, rainbow tentacles for 9000 robux worked with this method yesterday, what is the logic in this at all?
