Prevention to Scripthook

Is there a script that I can use to prevent people from stealing files when they join my server?

There is no point.

Nope. There will always be ways.

superiorservers blocked scripthook even before I join their server I got insta ban for malicious activity so its possible I guess

yes its possible to block script hook but its pointless, anyone can look at all of the client side files when they join a server.
