I think cheating is a very bold statement to make. Last night the server 'Was' actually lagging fairly badly since i was using my Phones hotspot which is good for about 8MB and it's very rare games lag on that. But i noticed people bouncing every now and then, i think what you saw there was mere lag. The Admins here believe it or not don't tolerate cheating to any extent and they'd have known supposing it was going down. King Boo has the cheat radar and brutally punishes those who do decide to cheat, supposing they escape the wrath of Garret
But yes. I really do think you saw an extreme case of lag, it's probably normal considering the server was shifted recently
