Meaningless Facebook requests?

yes, I searched before I asking. I’m getting too many friend requests in Facebook from people I’m not sure even I know. Maybe I DO know them and just don’t remember OR maybe we were born in the same hospital on the same day and they just want to re-connect.
Wouldn’t it be great if there were some setting in FB to send an automated response that says:
“I only accept friend requests from people I know or can learn something from. If you’re just collecting friends, trying to get me to listen to your band or want me to invest in something, I must respectfully decline.”

The key here is an AUTOMATED response so I wouldn’t have to deal with it. If not a Facebook setting, maybe there’s some kind of Applescript or Automator action?

Anybody know of anything?
