I doubt FM only had 3,000 transactions, and it was actually one of the oldest internet drug markets ever if you consider all of its previous incarnations. SR is probably one of the biggest (in member numbers) named drug networks in the history of the world, if not the biggest. But TFM was the biggest online drug market prior to it. It used to be that a forum with a few thousand members was considered enormous, before that a forum with a few hundred members was. The online drug scene is experiencing a truly exponential growth rate.
