How do I trace a spammer?

[WilsonTung]

I keep getting spammed by something called the 'Wall Street Bulletin' that hawks recommendations on penny stocks. This organization usually gets 200K shares as a bribe from a company. The organization then hypes up the stock and sells for a profit.

Their reply address is invalid. Their complaint and unregister addresses are invalid. How do I trace these people so I can nail 'em?

How does this help me trace a spammer?
