Mike I had that exact situation occur on a glove I put up. The "dad" ID user said his son erroneously bid on my glove. It was only a $25 sale, so I cancelled and got more money on the glove when I re-listed.
But, that said, user (dad or mom) is responsible for what happens on their computer ebay use. And with that, they're due a penalty if one wants to pursue it.
