Giving https://crossposter.masto.donte.com.br a try. This is posted to twit.social, my Mastodon instance, and, in theory cross-posted to #birdsite
@leo I have been doing this for over a year and its great. I mainly use my mastodon client to message on twitter. You can even host the service yourself if you don't trust them.
Fediverse win again.
@leo do you feel it is secure?
