I usually do it by editing in a curse-word, so that robomod will delete the post for me.
Wouldn't it make more sense to have DELETE as a clickable option, next to EDIT ?
It would also solve the problem for those people unwilling to type in curse-words because they believe they'll get in trouble for doing so.
My response is a bit TAME but someone could mess around with threads if they just kept deleting whatever they wrote...it takes all sorts but 'some' could get a kick out of 'post removed in response to post removed' notes...perhaps admin could do as they do with the 'alert moderator' icon, make it a subscriber only affair.
