Ok, you know those scripts/code thingys that you type on notepad and then when you open it up again, your computer does different things like backspace or open it's disc tray? Is there any possible way to post it on facebook and when someone clicks on the link it does that to their computer?

No. since you cant post files in facebook.

Well first of all, anything is possible. Facebook is a very secure site but I guess there can be scripts or programs created to auto post, I really don't know the reason for this unless it's advertising but Facebook allows apps to post on timelines, and these apps need permissions to post. So you could ultimately create a FB application to do this. But I find it pointless.
