Non-competes are almost always unenforceable. Never take money (although even then, they're still mostly useless), and just ignore them and no one is going to do anything. That was what my business law professor taught us. No court is going to enforce a non-compete if it means the person who cannot compete is going to be unable to support themselves. The only time it'll be enforced is if you're already independently wealthy.
In other words, a completely useless scare tactic.
