its quite simple, just like everything in this world, the larger sites have better supplier and connects...there are trillions of nps for sale at all times lol I know a bunch of sellers who have over 10 billion nps for sale right now all of which are not genned what so ever...websites like that are not hard to keep up with with illegit nps (not genned)...and there is no way on neopets to tell if an item is genned or not, your pile of dung in your inventory could be genned for all you know lol. so really i guess im trying to say the larger selling sites are just conglomerates of multiple large sellers working together to unload their massive stock of nps
