A conman is one who comes to an internet forum selling fake legal bullshit such as straw men, redemption schemes under the UCC, fake grand juries, etc. to people.
The conman probably works out of his parents basement and finds this avocation slightly more rewarding than his other side job which involves delivering pizza.
His dupes are uneducated, ill informed young men with lots of time on their hands. He gets to cause them to play governemtn from their mommy's basements.
But the ultimate litmus test is that most conmen are named "Joe". It is true!
