Polite thing to do is always ask if you want to draft someone.

If an idiot decide to draft off of me without asking, its a big "CLUE" that he doesn't know how to ride. I usually give the draftee a dirty look and if he still doesn't get it, I ride like Wilma until he goes away. Usually slowing down alot. I don't resort to snot rocket. Last thing is to piss off the guy behind you.

Being drafted by someone you don't know is very unsafe. Tell him to go away.
And kimmy's run in definitly gets my creepo alarm going in my head. If you are strong enough, drop him. And if you are not, stop and make a phone call. And even if you don't connect, pretend you are talking to your hubby or BF. Works like a charm.
