When the troll gets tangled up in his lies and obfuscation in a way where there is no way to move his argument further, he will create a diversion. This is also where the trolls agenda is mostly shown and the troll will begin talking about other issues he or she is having in order to divert away from the current failure.
And example is this, when Michael all of a sudden brings up a totally unrelated issue regarding a specific quote Steve has been posting in an issue that deals with whether Steve had commented on dreamweaver. Note how he claims to have moved the goalpost "back" while introducing a totally unrelated issue.
