Does it really matter? If someone tries to sell their duped high end items, whether it be now or 10 years later (if Neopets is still around), they will get iced. TNT has a good idea of who actually has the original 120 SuAPs that were released along with all the other high end items.
Someone already mentioned you are delusional, I guess I don't need to repeat again.
First answer this, how many FSS do you think are in the market in 2014? ALL are "legit" in the eyes of players and even TNT, prior to this event obviously.
Trust me when I say, no they are not. Half if not more are from 2005.
Faerie Accorn was 7.2m or 7.5m in HT when it retired. It was back in the years where 10m pure is Rich, 50m ~ 100m is mega unattendable rich. Not many users towered them.
I repeated many "Trust me when I say" throughout this board over the span of days. I'm assuring you now that when I mention that, I'm speaking from experience. So you can absolutely trust me when I said that. 
So there you go, an example of how user/TNT won't care in few months/ 1 year time. Much to say 10 years.
EDIT:
Well that said, it's also how you go about dumping your duped into the market. If the users are "careless", obviously they will get frozen.
