Unfortunately, he seems to refuse to react upon bug reports for fediverse.info, whether they come from the Fediverse or via Matrix.

Unlike Tootfinder, fediverse.info wasn't created for and geared towards only Mastodon; after all, it comes "from the makers of" Pixelfed.

However, it still doesn't work with Hubzilla. It does work with Friendica, but it doesn't work with Hubzilla. I've written @dansup a number of times via the Fediverse and once via Matrix. I haven't even received a reply yet.
