Suggestion: Mods to delete spammer's posts, without global delete permission

[Clickfinity]

I'd like to give my mods the power to delete spammers posts (people we mark as spammers using the ACP) - however, to do this at the moment I have to grant my moderators global delete privs (not something I want to do, to protect myself from a mod going rogue).

Would it be possible for moderators to be able to delete posts and topics ONLY for marked spammers?

Thanks,
Shaun :D
