Mark as unmaintained?

[rugk]

You can archive this repository, to mark it as unmaintained. People then cannot submit PRs and there is a big warning that this is archived.
Remember to add a note to the Readme before to explain that it is unmaintained, and – if you think this is useful – why and probably mention alternatives.
Maybe also take down the F-Droid listing or so.

…only if this is really unmaintained as speculated here, of course.
