Restrict from physically removing threads

[Danecookie]

Is there any mod which will restrict my staff members from physically removing threads? and posts?

I've checked the default VB option which restricts mods from physically removing threads but i think that option is not working as my mods are still gettin the option to physically remove the threads and many did.

I was amazed when i saw this because i've always thought it was OFF.

Please reply fast?
