As at least one of my polls has revealed, there seems to be a not insignificant number of Mastodon users who demand posts with over 500 characters be banned absolutely everywhere in the Fediverse.
That usually involves mentioning your channel. But unlike Mastodon users, users of Hubzilla or (streams) are not notified about being mentioned by random people by default, read, usually not at all.
If these very same Mastodon users can't read my posts anymore because someone else on their instance has talked their instance admin into blocking either my channel or the entirety of hub.netzgemeinde.eu, calling it inconvenient is an understatement.
