Hello @miamiuniversity.bsky.social , You should probably be aware that someone has compromised your organization and has attempted to notify you. They wrote to your I.T. department, but it was ignored. You should (probably) fix it.

Lengthy thread with lots covered, looking back and forward. Raphael is right on many things, especially for the bad press he got from people just blatantly shouting things without knowing the actual facts and details. But most important: Rafi, its great to have your voice back in the community!
