Sometimes the "time limited" usenet media isn't enough for the troll and his agenda, and he needs to create material in another media to antagonize other people, usually a web page. Michael has created several of these, of course, with the sole intention of antagonizing specific persons.
It is important to note that this very list could be called "antagonizing through other media" since it points to specific people, mostly Michael, throughout the definitions. BUt fact is that Michael himself requested this very list of objective troll criteria, and as such - it doesn't really constitute trolling.
