I wouldn't do anything rash.
Take a cheese pizza over to the address and look for the seller.
If you find the person at the address and get ID, tell them the pizza is free after they complete an informational survey. (Name, address, social security number, favorite type of pizza, etc.)
Get the person to sign for the pizza as that person.
Then, go down to the local police station and inform them that a person who committed several counts of felony mail fraud is in their jurisdiction.
If the cops want proof, show them this list of posts and your receipt.
If they're too lazy, pay a visit to the local FBI office.
