The statement "legally/illegally" may be construed as a threat, especially to a minor, and how the minor could interpret it. If he gets scared and thinks something is going to happen to him thats bad (gettin his butt kicked, etc.) then its a threat. The issue of intention and and interpretation come into play. As far as your location, thats sorta irrelevant. Some people have the ability to "reach out and touch someone".
Either way, in the end, you get a situation, once again, where a few, or one make the others look bad. In some ways requiring you be 18 to conduct a transaction would be a good idea, as there can be a higher level of accountability. Problem is, is that you will have some other teens, that get nailed because of this jack wagon, so their participation into this sport/hobby gets screwed. Method of shipping, and method of payment can be extremely important as well.
Maybe, since we know where the turd lives, the board/mods should scrutinize anything coming in from Olympia, dunno.
