Yes, it's currently quite time consuming to audit an instance. You have done a great job with your page and we learnt a few things.
We are only new to the #Fediverse (or Mastodon), but based on what we've read, it really should be called the Fediverse and not Mastodon.
Fediverse is a portmanteau (or combination) of the words "Federated" and "Universe".
Is good that you won't list instances that are too big or small.
