IP bans are only for 7 days, and Roblox highly likely won't do that due to said person possibly living in a apartment building and lets say people who live in said building also play Roblox, an IP ban would completely ban the everyone on the entire building resulting in other people getting unfairly IP banned.

So in short, if you somehow hack a Domino Crown into your inventory, I think you'll just be getting either a poison ban (shared email accounts banned) or just an ordinary deletion.
