Well, the answer to that last question appears to be six-and-a-half years. Kerry Haggard of Georgia was sentenced to six-and-a-half years in prison for faking vintage horror movie posters and selling them on eBay. Since he’s apparently bilked buyers out of more than a million bucks at this, it’s hard to feel too sorry for him, but still. . . imagine saying to your cellmate when he asks what you’re in for, “I sold some fake horror movie posters.”
That’s not going to earn you much prison cred.
