I prefer public trackers and torrents just because I don’t like gatekeeping piracy. I want those bits to be distributed as far and wide as possible. So anything I get and/or seed will be public.
Even if there are bad peers that don’t give back (which there are many), plenty enough times it’s just people with shitty under served Internet connections. I’m fortunate enough to have a good enough connection where that doesn’t bother me.
Just btw, while zstd’s compression ratio might be stronger, it will not be as fast as something like lzo-rle. When it comes to RAM you will definitely want to prefer speed unless you have a strict space usage requirement.
