I propose a new category of troll: the Oblivious Troll. These are trolls who do not even possess the level of introspection to realize that they are trolling. One example is Harmony, who has rarely, if ever, posted a positive comment about the Red Sox and uses every possible opportunity available to put them down. Jacko knows he is trolling IMO but does it anyway, so he is a "self-aware troll".
OTs....SATs......I like it.
