@tateisu@lemmy.juggler.jp PING!

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! @admin@aussie.zone).

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 FIRST, 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),
