  • I have identified two reasons for broken thumbnails right now:

    1. For some, the source website is simply not allowing our server to download the image (mostly due to server issues on the remote side)
    2. For others, it seems that some types of URLs are breaking thumbnail generation. I think I found the bug here and will try to submit a fix soon.


  • Yes, lemm.ee has all the standard Lemmy features. However, the format for this request has changed, and it seems the app has not been updated yet.

    For technical context: your app is trying to use the singular post_id field when marking posts as read. This field was marked as deprecated several releases ago, as it was replaced by a post_ids array field, in order to enable marking multiple posts as read at the same time. The deprecated post_id field has been removed in Lemmy 0.19.4.


  • Regarding your question:

    Lemmy federation basically works by copying stuff from their source instance to all other federated instances. So if I write a comment on lemm.ee, other federated instances will get their own copy of my comment. They will also all know that the “authority” for this comment is lemm.ee.

    If an admin on another instance decides to delete their local copy of my comment on lemm.ee, then they are always free to do so (for example, some instances might want to moderate more strictly), but any actions they take like this are limited to their own instance - for the rest of Lemmy, lemm.ee remains the authority for this comment, so individual remote instance admins taking actions won’t have any effect on any other instances.

    As for the original topic of modlog federation, basically it just boils down to this: just like with the comment example above, Lemmy instances also save a local copy of incoming federated mod logs. The Lemmy software does not yet have 100% coverage in terms of federating mod logs (for example, there are no federated logs yet for instance admins banning remote users), but this coverage has been increasing, and I expect this will eventually get to 100% (just needs more dev time really).

    Also, if some instance admins try to tamper with their mod logs, then other instances can still see the real history, because there is no way for an instance admin to delete copies of their mod log from other instances.



  • Most actions federate, any exceptions which aren’t federated yet are generally just there because the federation logic has not been implemented (but improvements are constantly being worked on).

    Generally federating the modlog is mostly just there for informative purposes. As in, we can check what mod actions were taken on instance A through the modlog on instance B (and there is no mechanism in Lemmy for other instances to retroactively remove or hide federated modlog items, btw).





  • Well, one advantage we have over commercial social media is that they need to pay people to write code and maintain the infrastructure, but a lot of work on Lemmy is volunteer-based.

    Many admins for bigger instances are basically on-call the whole year for free, open source contributors provide code for free, etc. Even the core maintainers are effectively losing money by working on Lemmy, because while they are getting some income, the sum of money they are getting from working on Lemmy is way smaller than what they would get if they worked typical software engineering jobs.

    Basically, if any non-volunteer organization wanted to replicate Lemmy, it would cost them quite a bit more in terms of payroll alone.

    Another aspect is scale - Lemmy is able to spread the costs between different instances, and while growth of the network can generally increase costs for individual nodes, they will still end up paying less compared to if they were hosting the entire social network in a centralized way.
