XF 1.3 Hide all of a user's 'stuff'


Active member
I have a user who requested that ALL his content be hidden, temporarily, as he is about to be involved in some legal stuff. While I don't imagine any content about the hobby forum matters for his case, I'd like to perform the request because he's been a solid member of the board for a long time.

my question is not so much HOW to do it, but more WHAT to do that doesn't create too much disruption.

So, what's the best way to do this? I don't want to delete anything... I don't want to over-load my mod queue...

things I'm planning to do already--
- change the username
- alter any user-identifiable stuff in profile

the last set is,
- set all his posts to moderated/hidden/something?
