Any judge should hold them in contempt and file a disbarment petition with the bar association if this happens on their watch.

Holding the lawyer in contempt and in jail unless and until they’re willing to name themselves openly for the record would be fine. I really like the idea of contempt meaning jail for obstructive behaviour, because it’s a “time out” for entitled adults.

This isn’t Twitter; it’s court. Rot in a cell or state your name for the permanent record.
