We'll need @askvortsov input to understand what he intends.
The Packagist package is called askvortsov/flarum-auto-moderator while the GitHub repo is called askvortsov1/flarum-automod. That's perfectly fine. The latest version from the GitHub repo seems to be correctly published to Packagist, so nobody is missing any update.
The package is marked abandoned on Packagist only and suggests using askvortsov/flarum-automod package instead, but there is no such package on Packagist. There's also no trace of that new package name in the GitHub repository.
While we wait for clarification I don't think there's any danger just ignoring the warning.
