@dansup @panos just noticed your listing of castopod showing 0 servers https://fedidb.com/software/castopod but I see that @Castopod isn't exposing nodeinfo at all right now so this obviously isn't your fault. looking here I see they did attempt to support it tho https://github.com/ad-aures/castopod/blob/develop/modules/Fediverse/Controllers/NodeInfo2Controller.php
cc @benjaminbellamy I would add this to your issue tracker if you happened to get a public issue tracker up somewhere.
