Right now it's too commonly accepted by the community to just cheat their way through every challenge, and that's not right, so based on that I'm in favor of people being banned for cheating (depending on the seriousness/frequency of offenses). Allowing people to cheat with impunity is certainly the wrong way to go, it sets a bad example and, perhaps worse, actually makes these poor deluded people think that they aren't even cheating (because Bungie allows it to go unpunished). That being said there needs to be proper communication because people need to have it explained to them that they've been cheating and it's not okay, if you just go straight to banning people after setting the precedent that cheating will not be punished then there would be a lot of collateral damage from people who didn't want to cheat but went along with it because it's what everyone else is doing. Also lots of people who cheat now wouldn't if they knew they might get banned for it, so even the threat of the ban hammer will help keep people in line. Part of the problem now is that there is no such threat unless you're modding consoles or something, and there's all sorts of cheating that's less extreme than that which deserves to be punished. And not to forget that temp bans can help fill the gap in punishments for offenses that don't warrant a permanent ban.
