Edit: deleting most of my comment because it’s a duplicate from the person who answered hours ago, leaving my indexers comment.

Something that you didn’t mention, but needs addressing - indexers. Yes, there are free indexers but they’re often capped at a certain number of grabs per day. Expect to pay for access to these as well - but some have lifetime memberships at a reasonable price. Get more than one and sabnzbd can prioritize by user-assigned weight. (By the way,these are typically what gets hit by content protection/LE). Indexers provide the nzb files that tell you download client where in the providers’ server to find the download bits/bytes.

The *arr stack works wonderfully with Usenet, I think if you go this route, you’ll be surprised how little you have to fall back to torrents.

It is, and it’s been revived! https://github.com/maforget/ComicRackCE

How do signal chats work if I already use signal with my full name? Can I say for a group chat to just use my nick instead?

But … that’s bok choy. 😟
