Because it is a scam, the toner isn't viable toner. The SJ Mercury news had a story on this during the great re-inking (people refilling ink carts, HP retaliating) and this particular scam was tied to people getting 'scrap' toner (which is they offered to dispose of unused/old/not-to-spec toner, got paid to do so, took it and poured it into plastic toner holders and then tried to sell it as 'oem' or 'extra fine' toner etc) There were complaints that it clogged printers, had smearing issues, and cost money to throw away. So the scammers were getting it on both ends, money to dispose it, and money from people tricked into buying it. The key here is that if there were a legitimate way/value to selling this toner they wouldn't be using it in their scam, they would just be selling it.
