It's not the resolution of tracker domains that's using up the quota but something about large peer lists and reverse DNS lookups. That's what AI tells me at least after I shared the DNS logs. And I have a huge list seeding obscure torrents over the years(~500) which might be exacerbating this issue. I already have an automation that resolves domains to fixed IP for common tracker list, so their resolution isn't many in the first place.
I think docker/podman like solution required if no way to set different DNS to qbt? But I don't know how complicated it would be to set targets to persistent storage in my PC.
