How can I stop the exploit "Infinite Jump"? [closed]

Hey, I was wondering if there is a way to stop the free exploit "Infinite Jump" from working on my game?

It abuses the sit and jump function, which makes you fly endlessly into the sky - you can try it in any game that uses a sit button, just sit and jump. But with Infinite Jump, you don't need a sit button - it's a program.

I cannot use FilteringEnabled, it breaks lots of my things, and it is not needed currently for me.
