Why should I share with you if you won’t share back? 99% of people do not upload anything to public or private trackers and a significant percentage don’t seed. Without those private tracker communities developing tools and working together to fulfill specific niches, none of that would trickle down to public trackers and anything but the most popular media would not be available to you. They ensure better quality and curation and I can have something I need uploaded through a request within a day a day or two because the members are motivated to share since they know it will be reciprocated. Anything I upload usually gets uploaded to public trackers by someone else, but I don’t feel any obligation to share things I’ve hand scanned and fixed the formatting on with random people on Pirate Bay.
