Don't think you understand , once you upload a piece of graphics into graal it technically becomes graals property in a way , the graal owners don't care about how ****ty their servers are so I don't see why they would even think about caring about custom heads being worn by other players because at the end of the day, people who " steal " these heads help diversities the customisation system of the game which only helps the company.
