A seedbox is a good thing. I switched to Ultraseedbox four years ago. The cost was only $5 more than I was paying for a VPN. I do most of my pirate activity on Usenet, but for some content, such as documentaries, torrents are the better option. The cool thing about Ultra, the cost includes complimentary HTTP proxy, OpenVPN and Wireguard. Source: about 1 year ago

If you don't mind torrents, then https://forums.mvgroup.org/. Source: over 2 years ago

I'm aware of docuwiki, I think about 30% of my documentaries come from there or from MVGroup, which is the main source for docuwiki itself. Unfortunately some of those sources are no longer being seeded, and/or only available on ed2k network, which is slowly dying :(. Source: about 3 years ago

The BBC doesn't go after pirates. Join MVGroup and get a bittorrent client, then go there once a week and get the latest documentaries (I'd stay in the BBC subsection). Source: over 3 years ago

The other option is the Caavo control centre which will likely become the successor to Harmony if they don't also go out of business through lack of interest. Source: almost 3 years ago
