Out of the few years I've been playing, I believe cheating in spar in any way is the worst it's ever been.

In my early days the staff had been better, and the only real cheat I always saw had been the speed hack.

Now people are getting creative and sneaky with VPN (Although I'm not entirely sure how it works, someone explain) I'm seeing people boost their speed slightly, almost unnoticeable if you don't pay attention, and I'm also seeing infinite HP cheats, too...
