Allen,
While "technically" I'd have to agree that it's not "ebay's problem", ebay does have a list of items that are on their banned list, such as firearms and porn. As I have stated before, I and others have sent ebay messages urging them to add trim tags to their banned list, but their response is that those tags contain no "vehicle specific" information like a VIN tag does. Of course they're wrong, because there are no two alike, but they've been blind to that.
Now that selling a tag is illegal in one state, I'd think they'd have to take notice and not allow the ad.
Ebay, swap meets, auctions, Hemmings, etc are not being put in the position of policemen looking for cars with questionable tags. But the simple act of selling a tag itself or accepting an ad for one for sale through their venue is knowingly allowing the law to be broken.
I would think a good "next step" would be to send a hard copy of the law (with a cover letter) to ebay, Hemmings, etc, then wait to see if they do the right thing. I would also be inclined to let Lynn decide on the wording and method for that "next step". I hope he will offer his opinion here.
