"""Mastodon_ is an open source alternative to large social media platforms like
Twitter/X, Facebook, ...
Since it's federated and self-hostable, there's a large amount of available
instances, which can be chosen instead by modifying ``base_url``.
We use their official API_ for searching, but unfortunately, their Search API_
forbids pagination without OAuth.
That's why we use tootfinder.ch for finding posts, which doesn't support searching
for users, accounts or other types of content on Mastodon however.
