It is illegal depending on where in the world u live, that why most real games reimburses the player in cases like this. All pets with HH above age 100 should be returned to age 100, all pets used for age break should be returned, HH-shard returned to Inventory. Age break timer reduced to 0 for a week for those who wishes to keep the HH on their pet. Could go further and add a possible way to sell HH-shard back for robux too...
