Ive been looking through meeting reports from the NUS - Jess Bradley was still attending meetings as part of the board in June 2018, with no mention of a Josh Bradley in the attendees.
In amongst the "worthiness" of student politics though, I did note that in June 2018:
"NEC Further Believes:
...
- The rise in online hate crime, including racism, islamophobia, antisemitism, homophobia,
transphobia and
misogyny must be fought at all costs." (my bolding). Not very often you get misogyny mentioned as a bad thing that should be avoided

.
Further down the report, Jess Bradley proposed a motion that (amongst other things) wanted a moratorium on building new prisons. They weren't especially interested (ie didn't propose or second) either of the sexual harassment within the NUS motions. Thought that was interesting.
