Yes this is a problem, bungie haven't mentioned hardly anything about these bans either which raises the question are these rumours true? From what I've heard is that there's 2 ghost shells, bungie apparently track people down with these and what's really strange is that these ghosts are supposed to be a ghost shell un obtainable (from what I've heard) to everyone unless picked up which causes you to obtain this mysterious ghost, this is supposedly an intrusion shell ghost, the reason this raises the question that these rumours may be real is the description of it reading, "rigged for eavesdropping, surveillance and intrusion into unfriendly networks. Ghosts can self-modify at will". Strange huh, oh yes and Kings watch isn't the only one with these ghosts, there's tons more unfortunately I can't name all of them but their all over the internet mostly using that sparrow glitch you talk about when mostly others use cunning parkour on ledges to reach. I highly not recommend going to these places though since mostly a lot of the stories often end with the mighty banhammer coming in minutes after and oh yes i almost forgot I also made a bug report on the sparrow glitch so hopefully when enough people finally report this bungie will most likely see it and work to patch it. Thanks for listening I know it got a bit big but hope it helps : D
