Yeah, if you're polite about it people will understand. I don't think you'll have too much of a problem if you think up solutions before hand. So instead of waiting for it to happen, write down now what you will do, what you will say to people if the wrong script is posted, and make sure you're very consistent about it.

Also, remember, if someone's script is posted without permission they might be mad, but there is always the possibility they would have posted it themselves. So every time you're contacted about a script it wouldn't hurt to say: "We're sorry your script got posted. We'll take it down immediately. A lot of people found it really useful, would you consider putting it back up under your own name?"
