XF 2.1 How do I put a user or thread on moderated

[ALJW]

I have a couple of users who are sometimes troublemakers - and I'd prefer to do "post approval" for them always, even if they're replying to an existing thread.

How do I do this SIMPLY?

Alternatively, set a thread to require admin to approve replies? (I don't want to lock it and stop replies, just monitor certain ones).

Set user specific permissions for Submit content without approval to Never.
