cross-posted from: https://lemmit.online/post/1047028 - because ironically this will not reach instances where Lemmit is blocked.

A few months ago, I launched the Lemmit instance and bot (@[email protected]). Primarily, this was to help me stay up to date with some of the content I'd leave behind on Reddi. Additionally, I wanted to give back to the community, so I made it possible for anyone to request the archiving of subreddits to the Lemmit instance.

However, this came with some unintended consequences. Notably, the most subscribed community on the instance has been [email protected]. Even though it should have been obvious that there is no way to communicate with the Original Poster, given they're on Reddit.

The pushback against the bot and the instance has increased over time. A recent post, This bot is bad for Lemmy, highlighted these concerns. I've also received similar feedback from admins of major Lemmy Instances and through direct PMs.

As a response, last week I stopped accepting requests for archiving new subreddits. This weekend, I went a step further by discontinuing the archiving of a large amount of "interactive subreddits"—communities primarily centered around Q&A or communication with the Original Poster. This includes subs like [email protected] and [email protected], as well as niche and support communities. Such discussions are better hosted on Reddit or Lemmy's equivalent spaces.

I've also adjusted the post karma thresholds to curb spam posts. While this probably won't appease everyone, it should reduce the bot's posting frequency.

Perhaps this might prompt some admins to rethink their choice to defederate from the Lemmit instance, or the banning of the bot. I'm not expecting anyone to, and won't take it personally if you don't, but I wanted to give the community this update nonetheless.

In [email protected] there's a sticky post of all the Actively archived communities on the server (including NSFW ones, since that is not public without logging in), as well as the list of communities for which archiving is now disabled.

Cheers!

I just had to delete over 44.000 Users, Bans and Activity messages from my database and defederate from lemmy.juggler.jp. Somehow, all their bans get propagated to the rest of the lemmyverse.

I did a quick check, and it seems like not all instances liked are affected, but some definitely are. aussie.zone, for starters (PING! @[email protected] )

The good news is that, due to the relational database, you only need to delete the users, and the database cascade does the rest. BEFORE YOU DO ANYTHING, MAKE A BACKUP OF YOUR DATABASE I am not responsible for messing up your database. Don't ever execute commands given by a stranger on the internet if you don't understand them. Also, unless you defederate from them, the logspam will just continue. So maybe do that first.

---

To fix it, get database access somehow, and check your instance table. There, search for the id for lemmy.juggler.jp with the following query:

SELECT id FROM instance WHERE domain = 'lemmy.juggler.jp';

Write down that id, and execute the following query:

DELETE FROM person WHERE instance_id=<the id you just wrote down>;

This will probably take a while (over 2 minutes on my database),

Lemmy starts out pretty chill, but the longer it is running, the more CPU it's using. Until I restart it again, and then the process starts over again. It's just /app/lemmy that's eating the cpu cycles. Looks like there are some threads that keep requeueing themselves, until eventually that's all it's doing.

Does anybody have any clues or pointers about this?

I'm running 0.17.4, haven't made the jump yet to 0.18.

Idea: Scrape all the posts from a subreddit as they're being made, and "archive" them on a lemmy instance, making it very clear it's being rehosted, and linking back to the original. It would probably have to be a "closed" lemmy instance specifically for this purpose. The tool would run for multiple subreddits, allowing Lemmy users to still be updated about and discuss any potential content that gets left behind.

Thoughts? It's probably iffy copyright-wise, but I think I can square my conscience with it.
