Trilby  filed a deletion request for mastodon :
The isn't even half of a PKGBUILD. Caleb apparently submitted several
half-complete (or less) and non functional PKGBUILDs almost a year ago
seeminly with the intent of getting feedback and hasn't done anything
If anything Caleb should have posted these on github or similar to
solicit feedback and help in getting them working: PKGBUILDs that are
known not to work should not be submitted to the AUR.
