Support / questions about Lemmy.
When I go to a community page (not signed in) I see thousands of subscribers, but when I access the community from within my account, I am shown dramatically less subscribers. I am a new convert from Reddit and don't understand what is going on.
Another community I wanted to join with 1.5k subscribers and lots of posts, came up as zero subscribers and no posts when I searched for and went when signed in. It showed that it was the correct community page, but nothing there.
Am I on a bad server?
The subscriber count you see is how many on your instance have subscribed.
There are typically more, which is demonstrated by the screenshot you put up.
Ah thanks, it was quite confusing. Maybe a little note on the interface. Do you know where I could make this suggestion?
I expect that it has heen made. Even better would be for the actual number of subscribers, or at least an estimate, would be better.
I think the lemmy github page has an issue tracker that you can add it to. (Sorry on mobile)
Worth noting that some of this isn't always 💯 possible. If some instances have blocked other instances where users have interacted with a post, your numbers and their numbers will diverge. The host of the content generally will have the most complete numbers, but it might be possible for that to be wrong if the server doesn't have authorized fetch enabled (ie: server a has content, blocks server b, server c boosts the content but does not block c, c boosts/upvotes/favorites it. A now doesn't know about any metrics from server C, despite being the original source of content).

For clarity sake... is this on the same server, is your browser on the exact same server before and after login?
No, now I understand that I will be shown the number of people subscribed on my server when logged in. But I still don't understand why I cannot see posts made before I subscribed. I can see them on other communities and comment. Is that a decision made by each community?

I don't understand, and I think that would actually be some kind of bug. If a specific server shows different numbers logged-in vs anonymous.

Are you mixing up the words "community" with "instance"?
Instance means server. Lemmy.ml vs. Lemmy.world
Community means topic, such as !historymemes@lemmy.ml is a community
A Community has a "home instance" (server) that is where the community first originated and was created. Typically the home of a community is where the full copy of all comments, posts, votes are kept. But I suppose it is possible for even them to purge content to save storage or improve performance (or some other reason).
A Community can be subscribed to by remote instances. This is where there is a lot of end-user and new admin (new isntance) confusion. It is not automatic to get all content from all other instances. The very first Community subscriber on an Instance starts the flow of content from the "home instance" of a specific Community to this specific now-subscribed "remote Instance".
ALSO NOTE: there are bugs in Lemmy "replication" logic. Such as delete of a comment not going to all Instances for a community. As of version 0.18.2, the actual side-by-side comparison of two instances for the same Community can such show inconsistencies. I have persoally run such comparisons with !lemmy_helper@lemmy.ml code.
Back to what you said:
I still don’t understand why I cannot see posts made before I subscribed.
If your remote instance has never had a subscriber to that specific Community, flow of data begins at the time of your subscribe. It does not do what is called "back-fill" of votes, comments, posts that may go back 4 years of Lemmy servers being online.
Does that sound like your situation?
I think I got it now. The reason I saw history from other communities on my server is because others had subscribed (from my server) and started a history for my server from the time they subscribed. In this case now, I was the first and so no history. Is that correct?
Also when I see a very low subscribed number for a community on another server (from my server) it is because that number shows how many people from my server are subscribed only. When I visit the server where the community is hosted and see a large subscribed number, does that represent the total number of subscribed to that community across all servers or the number of subscribed only for the server that hosts the community?
Thanks
