Also not sure if you’ve ever been part of a private tracker but there a much higher percentage of users have additional motivation to contribute. Some of that is because contributing provides additional benefits to consumption. But also it’s for the love of the game. The losses of oink and what.cd were a bit like the burning of the library of Alexandria. Those libraries were the cumulative effort of tens of thousands of people sharing and meticulously cataloging. Much closer to maintaining a library or an archive than something like TPB. There is no doubt there is music that is now lost to time which was once dutifully uploaded and then preserved by a seeder on those sites. I personally have uploaded content that is not available to purchase anywhere to their successor.
