The good news is that many of them have left academia (e.g., this one, this one, and this one), some self-destructing in a way consistent with their online antics, others just failing to find academic positions.   Alas, some of the juvenile jackasses remain in the academy, at least for now.  Let me add that the only ones who ought to have their online stupidity held against them are those who are openly hostile to academic freedom.  There are enough threats to the latter without multiplying them from within the academy.

MARCH 18 UPDATE:  A reader just flagged for me that the aforementioned juvenile jackass, Dallas Jokic, offered this response (on Twitter of course) to the original post:   "It is very strange indeed that a prominent philosopher is gloating about his graduate student critics having left academia following his bullying of them. Stranger still that he seems to view this as a victory for 'academic freedom.'" There really is no bottom to dumb with these pathetic people: none of the three who have left academia were critics of me, let alone "bullied" by me or anyone else, and all three made clear their hostility towards core academic freedom values, which is why their departure is good news for the academy.
