Agreed. Bartering awards is against the rules of every program I've looked at. The airlines are not exactly unaware of eBay, Craig's List and the rest. They have enforcement units who make examples of random violators. Those folks are good at their jobs. Penalties include closing your account and confiscating all your miles/points - not just the ones you tried to sell/barter. If you use a ticket obtained this way, you may show up at the airport to find it cancelled, or show up for the return trip with no option but to buy a one-way ticket at the last-minute walk-up fare to get home. IMHO, it's not worth the risk.
