Doing this is far worse than cheesing Atheon. Cheesing Atheon was a result of terrible and daft game testers and creative and innovative users. Doing the bridge glitch and the chalice glitch is not even bad like the DC glitch. It's all within the game and they never figured it out in testing. It's also something they can address and patch. The DC glitch is exactly what it's described as, a glitch. It's not cheese like the other tactics. Are they all examples of poor sporting? Sure but only one involves altering your connection to improve/beat your odds at a reward/loot. This is no different than using a lag switch back in the day for FPS. I don't know what mechanics are in the game that freezes a boss when someone disconnects but you can be sure these people are testing this with all forms in the VoG and other missions as well (nightfall, etc). With all that said, banning people will be tough without a foolproof way to discern who did it. I am sure 75% of the Vex Mythoclasts out there are cheesed but that's neither here nor there now. Hell, Bungie even joked out how many times Atheon was cheesed. You can't unring a bell.
