@lanodan We have issues with importing stray items when they aren't delivered via PuSH :)
What you're asking for is a good feature. It's just that we're all volunteers, so it's sometimes hard to find the time. If you want to, you can add it to the issue list on https://git.gnu.io/gnu/gnu-social/issues
You'll need to create an account since # sucks and can't use OpenID providers for authentication.
