Hard delete for visitor messages.
 

When someone spams your visitor messages with dumb stuff I either have to leave it for fill my wall with "This messages was deleted".

Just thinking that it might be nice to have a hard delete option where you can just erase the messages like you've got the GetDare infinity gauntlet

Yeah that would be good. Other people can't see "this message was deleted" on your wall, only you see that. But is annoying.
