⚒️Thor, the Norseman⚒️ @thor

There must be a person on Mastodon that I've favourited more than every other person. I'd like to know who that person is.

@thor You can fetch and analyze your favs via API.

Using the Mastodon Python wrapper this simple script returns a quite raw output, just printing lines with the number of toots you faved and account/display name and user url like:

"14 ('thor', '⚒️Thor, the Norseman⚒️', 'snabeltann.no/@thor')"

This should answer your question.

@encarsia Well, yes, as a developer, I could do that. Now solve it for everyone else.
