I've reinstalled lemmy several times and after I went public with my instance, I figured out federation is broken for those posts with a low id, because those posts got federated and after reinstall, they have been ghost data and no sync happened.

Now, I've figured out that almost every post is broken and doesn't federate correctly. It shows the wrong posts on different mastodon instances.

Will a new installation, BUT with a new subdomain solve the problem?

If yes, will it be possible to move all posts to the new installation without breaking anything or do I have to rewrite every post?

I've created a question about the moving posts on Github, too.

I've set up a Lemmy instance and tested federation by commenting with my Mastodon account on the lemmy instance, which worked.

But I broke the test instance and had to start over (not even once).

The productive instance runs now, but after a few days I figured out that there is still the old post from the old installation on Mastodon and over Mastodon I can't see the new post and no new comments?

It is the same link (older Mastodon post, old Mastodon post, new Lemmy post), but the content is different.

• The post itself doesn't update (it is completely different)
• The comments don't update (different comments)

How to solve this problem? Is it even solvable?

I'd like to create a safe space without distraction and a focus on specific topics.

But as soon as a user from my instance posts or reacts to something outside of my instance, a lot of data gets transferred and everyone from my instance will see the post in the "All" timeline.

This could lead to a lot of distraction pretty fast, especially people with ADHD could lose track if they see some interesting stuff from other instances. I want to avoid this and give them a safe space to be able to focus.

The only way I figured out was to deactivate federation at all. There is only one button in the settings.

But I would like to keep the feature that people could comment from other Fediverse tools like Mastodon, Kbin, Peertube, etc., but it doesn't work anymore, if federation is deactivated.

Is there a way to keep away all federated content from other instances, which got in touch with my users (proactively cross-posted stuff is okay), but keep the feature so people from other instances could post something?

And it would be okay if my users comment on external posts, too, but not all people on my instance have to know it or get distracted by it.

Thank you for your help :)

I've installed Lemmy via ansible, but I figured out that there are problems with emails and after I've created a user, no verification email came, no login is possible and now I have a ghost account I want to delete.

Because I couldn't find an UI element to purge users in the admin panel, I want to do it over postgresql, but I have no idea how to connect to the Lemmy database over a docker container, only thing I've found is to backup/restore the whole database:

docker-compose exec postgres pg_dumpall -c -U lemmy | gzip > lemmy_dump_date +%Y-%m-%d""%H%M_%S.sql.gz

Thank you for your help.

Because of copyright laws in my country, I want to get rid of the option to upload images on my instance.

I thought it would be the fastest way to just remove the "upload image" icon from the tool bar. But it's harder than I thought, because I can't find it...

I've installed Lemmy with ansible and it runs with docker containers.

How can I get rid of this icon or even better, the function to upload an image?

I already tried to stop the pictr container, but this avoids uploading icons/banner for communites and thumbnails for new posts will not be generated, which is a no go.

I only want to get rid of the upload option while creating a new post.

Thanks a lot for your help :)

I am trying to figure out how people can subscribe to a Lemmy community or Lemmy thread?

It might be possible to see a community on Mastodon if you copy the link (example: https://lemmy.ml/c/lemmy_support) and paste it into the search field on Mastodon and then you can hit subscribe and even activate the bell for notification.

But nothing happens if I do that.

Can someone confirm that it usually works like that, but it may be a problem of my Mastodon instance?

Is it possible to subscribe to threads, too, e.g. like this one here I wrote (without being the creator of a thread)?

I would really like to go public with my Lemmy instance, but if this doesn't work, it's a no-go.

I don't know if it's okay to post Mastodon links on a Lemmy instance, but I wanna try it and because I am really proud of this piece, I want to share it with everyone :)

It took almost one week to complete and it was the first time using more than one color.

With lemmy it is possible to upload any image to the lemmy server (including archive websites), while writing a post without even posting.

This could be used to upload pornographic, right winged or other illegal content and use it or share it on other platforms, even if the content is on your lemmy instance.

In Germany advocates even use archive.org as an evidence that you had illegal content on your website, including the exact date.

This could be very expensive for everyone who is managing a lemmy instance.

Another problem with the upload is, that a lot of images can be uploaded, without even using them in a post, just filling up the server with garbage data. Attackers could use this to automatically fill up the web space and provoke a crash.

Who is the owner of uploaded and shared images and posts? If a lemmy post gets shared, a copy of the image will be created. If the image doesn't have a share-alike licence, the owner of the instance could get in trouble.

I am not an advocate! Those are just things I thought about, which could cause trouble if I would have a lemmy instance.

Once there was a time were applications weren't forced to go online, because not everyone was able to be online. You needed registration keys for most of the software and at this point the demo scene came in.

I really like those key gens (key generators) with a small 2D or even 3D animation, midi sound and the actual key generation.

But like 10 years ago, Windows (or was it an antivir app?) started to delete those without asking me, because it recognized it as malware (yeah, sure...)

I once collected them, because for me they were some kind of cool collectible art (not like this NTFs bullshit). But I lost all of them at once.

Is there someone who collects them or is there even a publicly accessible place to watch them?

btw. stuff like this was one of the reasons to never use Windows again.

I will rent a v-server today with those specs: 2 CPU cores, 4GB RAM, 80GB disk space

I think it's enough to run normal websites and even a game server, but I have no experience with the Fediverse.

Is this enough to run a few fediverse instances, like Lemmy and Mastodon or even others?

How much resources does Lemmy need in particular?

Thank you for your help.

I am looking for a fediverse solution for a blog and I tried it with writefreely, but it has some disadvantages I can't live with.

The most important one is, that it should be possible to communicate with people within the fediverse. People should be able to comment on every article with a fediverse account, like it is already possible between Mastodon, Pleroma, PeerTube and others. But comments aren't a thing with writefreely and this is sad.

After using Lemmy for a few days I just thought if it is possible to use it as a blog and ask on lemmys github if it is possible to restrict a group so only one person could post new articles, but all others can comment. And the answer is yes!

But would it be possible to use it as a blog?

Imagine I would have a group called "utopify.org - Research & Development" and would post current progress about a blog series and you can only comment on it. Would it be possible and would it be something you want to see on Lemmy or would this just be an abuse of the software.

If all of this is just a no-go, are there other ways in the fediverse to have a blog article, which can be shared on the fediverse and be commented on?

I want to find the most sustainable operating system, because computers nowadays waste a lot of energy, because of data collection and data processing. Avoiding unnecessary processes and using resources in a mindful way could reduce the CO2 output on the whole world.

This discussion grew very fast and I put all links to other platforms in the end of the blog article.
