Able to reply to closed threads?

[Blakefire]

I noticed some of my staff can reply to locked threads and I dont see a permission for this. Anything I can do?

If the moderator has permission to lock / unlock threads then they are also allowed to reply to locked threads. This is the controlling permission:

Admin CP -> Users -> Moderators -> [click the moderator] -> Lock / unlock threads
