  Maybe they unzipped the archive? /S

  ¯_(:-)_/¯

  I don’t know exactly how that post counter … actually, technically counts posts, but:

  1:

  Zip going down could have uncounted all posts anywhere made by zip accounts.

  2:

  There could have been some kind of… propogating post count negation effect, as various other instances reacted differently to zip users posts on their instances could not pull them anymore, on different time scales.

  3: If a zip user had a … top level comment, on another instance, its possible all lower level comments responding to that comment may also have poofed out of existence, in some respect.

  I may be using some terminology here, and this is just spitballing, but yeah.

  Almost all of my .zip account’s posts… are not on zip itself, and its possible that that is fairly common amongst .zip users.

    i apparently cannot figure out ascii shrugs, nvm

    Just so we’re clear, what this crawler does is go through all servers that use ActivityPub known to it, and congregate that data to a list of known services (Lemmy, Mastodon, Piefed etc.). How is does that is by querying a standardised end point to get the instance info (.well-known/nodeinfo which will then point to a different path to get the actual info).

    For instance, here’s what it will collect for feddit.uk:

    nodeinfo json

    json // curl -s https://feddit.uk/nodeinfo/2.1 | jq { “version”: “2.1”, “software”: { “name”: “lemmy”, “version”: “0.19.10-feddit”, “repository”: “https://github.com/LemmyNet/lemmy”, “homepage”: “https://join-lemmy.org/” }, “protocols”: [ “activitypub” ], “usage”: { “users”: { “total”: 4184, “activeHalfyear”: 718, “activeMonth”: 485 }, “localPosts”: 25750, “localComments”: 122835 }, “openRegistrations”: true, “services”: { “inbound”: [], “outbound”: [] }, “metadata”: {} }

    The important stat here is the localPosts, which is all the posts made by local users in any community, local or remote. It does not include posts by users from remote instances made in local communities. You can also see this data on the instance sidebar in lemmy-ui.

    lemmy.zip going down will only reduce aggregated stats for total posts by 47,280, as that’s what they report for their localPosts.

      Huh.

      Well, I appreciate the info and shrugging magic, but uh… hrm.

      I dunno then.

      Do comments count as posts? Because losing all comments from an instance would probably explain such a huge dip
