I second the trust issues vote.
I'm the kind of person who believes each person is accountable for their own actions, so I don't worry so much about enabling someone to cheat. What I do worry about is being lied to.
If you know someone is going to be cheating, then there's no reason to believe they'll ever be open and honest with you.
So no, I wouldn't.
