Nothing wrong with how the leeching system works on privates. I quite like it, in fact. It's just that private trackers are very often a "who you know" kind of affair and that requires sitting in IRC, forums etc. which is something I can't justify doing on the random chance I spot a tracker doing signups.

Any private trackers that do have open signups seem to have too few users to keep new content coming through at a decent pace. I use DigitalCore, for example, and a lot of their content is just nonexistent compared to RarBG (RIP) with less seeders on anything that isn't brand new, and the only new stuff is usually concentrated on stuff already seeded ad nauseam on public trackers.

It's a shame RarBG went kaput because their system was fine... when it worked.
