Remember, a troll needs attention to his trolling, so whenever he is in a lengthy thread arguing only with this one poster, the troll is likely to break out of that thread and start another thread that will be one way to evade the first thread and also draw more attention from more people. An example of this is this thread where Michael creates a completely new thread which is totally off topic and an off-spring of a length discussion he's had with Steve and Elizabot.
