Based on monthly users, Hexbear should be 7th, but we're listed as 9th.

Also, there's no users graph on Hexbear's the-federation.info page, either.

lemmy.ml's graph, for comparison
I'd be a little surprised if it isn't some bug. We're listed on Feddit's Lemmymap, even though feddit.de pre-emptively defederated from us.
Hexbear also wasn't listed on join-lemmy.org/instances until Nutomic told us that his crawler was hitting a syntax error when trying to parse Hexbear's version,
0.18.3.hexbear.2at the time.
