I think it would be a good idea to add a separate setting to disable direct chat messages - I am forever having to ask people to PM me instead as it’s easier for me to refer back to and keep track of conversations that way. Pretty sure admin and mod team members of other forums might feel similarly.

FWIW I think separate options for each would be a good idea.
