Mr. "John Hogan" is a typical Internet troll. He does not have a genuine interest in the questions he asks.
His interest lies in revving up Internet communities, and judging by the fact that he uses tricks that are the very foundation of the troll arsenal, this is definitely not the first time he has trolled an Internet forum.
On some more active Internet forums, where this type of trolling is far from unusual, and it's encountered on regular basis, the moderators have toughened up correspondingly, and trolls are banned on sight, because it is clearly understood that nothing good ever comes of their presence.
An excess number of trolls can kill an Internet community, and one needs to look no further than AikidoJournal's forum.
