I'm not sure but I think Stefan's thing checks the speed that the game is running, not the player.... Not really positive on that though.

A solution would be to use scripted movement, with pixel perfect speed. Then you can do serverside checks of the speed to see if it's over a certain value. That usually solves the people who are editing their walk speed with other programs. But a lot of people use those program speed increasers which just increases your entire program's speed. (it makes everything like it's in hyper mode)

If Stefan's script is detecting that, then you're pretty much preventing people from speed hacking, with the combined two safety measures.
