Who are we?
We are digital librarians. Among us are represented the various reasons to keep data -- legal requirements, competitive requirements, uncertainty of permanence of cloud services, distaste for transmitting your data externally (e.g. government or corporate espionage), cultural and familial archivists, internet collapse preppers, and people who do it themselves so they're sure it's done right. Everyone has their reasons for curating the data they have decided to keep (either forever or For A Damn Long Time). Along the way we have sought out like-minded individuals to exchange strategies, war stories, and cautionary tales of failures.
We are one. We are legion. And we're trying really hard not to forget.

MakeMKV can rip the DVDs without touching the contents. I'd suggest either an ISO or more helpfully the contents in folder layout which should be preserved under a top level folder with the name of the disc and at the bottom level .vob files.
You certainly can use Handbrake but it is re-encoding and if you have no experience it's easy to mess up (among other things de-interlacing doesn't always work right without tweaking so it's typically best for archiving to not re-encode DVDs before sharing).
-If- you do chose to use Handbrake (again I wouldn't recommend it if archiving, it takes skill and there's a reason why to this day full DVD rips are useful to people who want a copy while someone's best attempt at an AVI file made 15 years ago looks awful and is considered useless given the low bitrates and old codecs) I'd plead you use software not hardware encoding, choose x264 or x265 (10bit for x265) and use the slow preset at CRF, constant quality 16 and make sure de-interlacing is set right on auto, also pass through the audio in original dolby digital as well as vobsub subtitles. But it really is best to not encode and just copy.
You can share directly to the DHT swarms by just creating your own torrent and eventually people will find it assuming it's named correctly in the format of <movie name (year)>.
Don't duplicate other people's work if you can help it. There are various sites for sharing this type of stuff, I don't want to get in trouble so won't name the one but there is one listed in the piracy community megathread, a Russian one, semi-private. I would search disc titles first to make sure what you're doing doesn't already exist and focus on archiving and sharing original non-re-encoded copies of those which don't presently exist elsewhere.
