Hello dear ROBLOX, *Me and some friends are making a ROBLOX game and then there’s another player who is like one of Owner friend but then they broke there friend relationship because of this. This other guy username on ROBLOX is YtShadowDragon*** after we broke our relationship with him he somehow has copy’s of the game and he then started his own game based of my old friend game he got that copy and now he’s continuing it and he’s posting some stuff from my game on his game saying that it’s his and he’s also threatening me and my friends that are owners that he will leak my game and give it away. But not only this problem the problem is old days he used to come ask me to send him copies of other games so he says it’s his and starts a game out of no where using those models he got. So please if you can do something about it please do because my community doesn’t know about this and they waiting for the game and if he leaks it people will be start saying bad stuff to us.
