I've had one running for over a year now, it's replaced my usage of regular torrent sites completely, there is a lot of junk, and it gets stale, but it's still a better experience than most of the public trackers out there IMO
How much space do you need to store the index?
Same here, for over a year. how many torrents has yours indexed?
I disabled mine because it was constantly writing to my SSD.
Are you running it at home?
I built one with a nice TUI to run on a VPS so I can try and find rare magazine torrents, but Hetzner were upset about it. I need to find it a new home. It was a very good citizen, but it still raised too many flags.
