Personally I use public trackers the most and only recently private trackers for stuff in my native language.
I did setup i2p a few days ago and currently have only downloaded around ~1GB. Most of my bandwith (143 GB in / 135.5 GB out) has come from just having it in the background 24/7.
The advantages of usenet don’t really apply to me (longer retention, faster speeds, no vpn)
Streaming i find useful for checking if something is worth downloading
Yeah I’m basically back to 2012 with public torrents and ripping from streaming websites I don’t trust very well. And downloading to an external hard drive that very well might die on me and ruin my day eventually.
But now I have a jellyfin server to watch it on, so I got that going for me, which is nice.
