Spam Question Removal from Forum post

Question

Sometime I can see there are spam questions on forum and generally I mark them as spam but at the same time when I refresh page there I can't find any mark identification that question has been marked as spam by someone.

 

I want to immediate removal of spam question or hide them until admin review. Any clarification on this would be helful to all regarding spam questions.

 

Admin can add restriction or filter to adding some spam words.
