To hide the troll everywhere:
[class$="<userid>"], [class$="<userid>"] *, [class$="<userid>"] :link
+, [class$="<userid>"] :visited, a[href$="=<userid>"] { display: non
+e; }
This css rule occasionaly hides responses to the troll, too (e.g. in Recently Active Threads).
update: to mark troll posts as such in threads
[class$="<userid>"], [class$="<userid>"] *, [class$="<userid>"] :link
+, [class$="<userid>"] :visited { display: none; }
a[href$="=<userid>"]:before { content: "a Troll: "; }
I can't get rid of the troll post header with css, because there's no way to select a parent node matching a child.
