Did you/he report the players? Bungie does take action on these things if they find it serious enough. Reporting is the best bet in this situation. If your little brother needs help and he is on the xbox1 system, myself and someone from my clan will help him. Sorry this happened to him but the best thing we can do as honest players is report them to someone with the power to do something about it so this doesn't happen to someone else. For those on here saying things like "that's life" are part of the problem. Online gaming should be a place where everyone can have fun regardless of age. This type of thing needs to stop now, that is all.
