I tried out my first private tracker with SceneTime.

Literally no benefit over a public tracker that I can see.

Selection is smaller, all torrents have a max of 30 seeders that I have seen. Most have 2-3.
Impossible to get a good ratio without seeding an unwanted popular torrent because niche content will have like 3 downloads per year.
Tons of abandoned torrents or torrents with 1 seeder
Almost 0 content older than 10 years unless it is very popular

Maybe I am not integrated enough with the community, and my stupid ISP has extreme asymmetrical speeds that max my upload at 30Mbps, but I mostly still use a public tracker where when I seed, people will actually leech.
