Path forward is to build as close of a replacement as possible on https://atproto.com/ otherwise the enshittfication dance always continues. Doesn't have to be perfect, it just as to be able to avoid corporate capture, like water running through clasped hands. https://atprotoalternatives.com/ Historical Reddit data remains available via torrent: https://github.com/ArthurHeitmann/arctic_shift/blob/master/d...
In Reddit is killing RSS feeds and ending public API access because of AI bots
I cannot answer this question, but you can always run your own instance scraping X, serving it as a pull through cache, while creating torrents to serve of the archive, all from outside a jurisdiction Musk can get to. If you're paying, you're contributing. https://news.ycombinator.com/item?id=49481557 (potential durable architecture subthread discussion) https://github.com/ArthurHeitmann/arctic_shift | https://github.com/ArthurHeitmann/arctic_shift/blob/master/d... (Reddit example, with the archived datasets available on AcademicTorrents)
In Is there any way to contribute to nitter and xcancel's legal fights?
the data from 2025-12 has been released already, it is usually released every month, it just needs to be split and reprocessed for 2025 by watchful1. i will probably eventually add support for importing data from the monthly arctic shift dumps so that archives can be updated monthly. https://github.com/ArthurHeitmann/arctic_shift/releases Arctic Shift https://academictorrents.com/browse.php?search=RaiderBDev Watchful1 https://academictorrents.com/browse.php?search=Watchful1
In Show HN: Self-host Reddit – 2.38B posts, works offline, yours forever
That's pretty neat! I did something similar. I build a tool[1] to import the Project Arctic Shift dumps[2] of reddit into sqlite. It was mostly an exercise to experiment with Rust and SQLite (HN's two favorite topics). If you don't build a FTS5 index and import without WAL (--unsafe-mode), import of every reddit comment and submission takes a bit over 24 hours and produces a ~10TB DB. SQLite offers a lot of cool json features that would let you store the raw json and operate on that, but I eschewed them in favor of parsing only once at load time. THat also lets me normalize the data a bit. I find that building the DB is pretty "fast", but queries run much faster if I immediately vacuum the DB after building it. The vacuum operation is actually slower than the original import, taking a few days to finish. [1] https://github.com/Paul-E/Push

In Show HN: 22 GB of Hacker News in SQLite
Reddit's caches are set up to only ever return the last 1,000 of anything. So for example - you can't scroll past 1k items on /new, and if you save more than 1k posts then you'll have to unsave some to retrieve the others. If this extension only edits comments, it'll only touch the most recent 1k. You would need to retrieve the older ones with a Pushshift replacement like this: https://pullpush.io/. But that also shows how ineffective this is. We still have public reddit archives (like Pullpush and https://github.com/ArthurHeitmann/arctic_shift) which contain comments as they were originally posted. This isn't gonna be a problem for Google.
