I can see this community in my feed but at the same time this community can't be found. Is there something wrong with my instance?

Hello everyone! I'm experiencing troubles with federation with other instance. I get a lot of operation timed out in logs

I get this from many instances but ping to them works just fine. I can't even add new communities now. I've increased federation workers but to no avail

So I have set up my own Mastodon instance and it's empty. What should I do to fill up my instance with content? And how do I do that other users of Mastodon on other instances see my "tweets" on my instance?

Hello everyone! Recently I have removed a couple of bot users from my Lemmy instance via DB query (I removed them from person table). Those bots were subscribing to hundreds of communities on other instances which I don't really want to spend resources on fetching new posts and updates.

I have purged those communities from my instance but they keep reappearing. As far as I can tell, this happens because other instances still "think" that users from my instance (bots, which don't exist already) are still subscribed, and therefore send updates to my instance.

How can I completely get rid of those communities?

Hello everyone!

Recently my instance have become a target of community subscribers bots, which subscribed my instance to hundreds of communities. I've deleted all those bot accounts manually and enabled captcha and application for registration.

Then I stopped all containers except for lemmy-postgres and ran a following query to purge all empty communities

delete from community where id in (select community_id from community_aggregates ca where ca.subscribers = 0 for update skip locked);

At first I thought that it worked because all communities and related posts have disappeared, but when I started all the other containers, lemmy for some reason again started adding back those communities with 0 subscribers to my database.

What am I doing wrong? How do I purge them? Also, I would appreciate on any guide how to remove all dangling images (which don't have any reference from db) in pict-rs.

Thanks!

There have appeared hundreds of communities on my instance I have never searched. Where do they come from? Is it some spam attack? How do I prevent this, and how do I get rid of them?
