You could create special missions for the short content platforms, to attract their users too to Liotes. But that's more work for you guys.

The easy option would be to share this mission post over there on all of them. Maybe the stats post from Monday too. But not sure these are acceptable practices on each of them. On Threads you'd have to add the link to a reply, it doesn't work as a top level thread (or it didn't back when I was more active over there on Threads).
