Björn BrembsYES!
This is precisely what every university (and scholarly society!!) should be doing: have their own instance and drop X like a hot potato:
"an instance has been created [... ] on university servers, which is open to the university's organizational units. The active use of X will be significantly reduced."

University of Innsbruck focuses on Mastodon
The communications team at the University of Innsbruck will increasingly rely on the microblogging service Mastodon for science communication. Mastodon is a non-commercial and data protection-friendly platform with functions similar to the former Twitter. For this purpose, an instance has been created at social.uibk.ac.at on university servers, which is open to the university's organizational units. The active use of X will be significantly reduced.
