just wondering, I tried unsubscribing to several threads, but they refuse to die, how is that possible?

and how do I do it, since I want to add new life to several of my blogs, that I feel were ignored

offending posts
death at Blackbeards
fresno &list noque?
ghosts
laucks died

looks like a pattern here?
is there a key word that gets posts on ff extra life, by repeating them ad nasium?
is there a ghost in the machine?
