De facto, maybe, but where does it specifically say in the regulations that you may not possess, for noncommercial purposes, such-and-such make/model of radio, of any vintage? It doesn't. But now it seems that we just moved one step closer to that. The key here is whether or not the boards and publications could reasonably have been expected to know that the sales being facilitated were, in fact, illegal under whatever regulations existed at the time. In those cases where the board or publication was found liable it was because they could have reasonably been expected to know that what the seller was engaged in was illegal. If someone posts one of those 11M POSs for sale, one time, no big deal. If the same individual posts the same or similar 11M POSs for sale on a regular basis, alarm bells would (or should, at any rate) go off and further inquiry is warranted.
