It's also pointless, especially here, where someone can post anonymously or just create a new account. Here at PM, the best option we have is to ignore the troll. And I personally do not have a problem if Monks use some web magic to make that easier. For me, i will still see a node is there, just not the contents unless I drill down into the message. Specifically, this is the code I'm using in my display settings:
tr.pmnote-<monkid_goes_here> { display: none; }
