@Setanta,
Stop playing games. Your opening post made clear your intention with this thread and exactly who you were talking about. You wanted to know why people were continuing to respond to this particular troll.
Whatever you said in this thread after that doesn't change your initial post which describes your intention with this thread. You created another thread about him, and asked why people continue to feed him. And, in so doing, you were feeding him. Claiming he has you on ignore, and therefore he wouldn't see this thread, is a rather lame excuse for devoting another thread to him and asserting you weren't feeding him.
In your response to Punkey you simply broadened your initial question a bit beyond, "the one whom i have in mind"--reiterating that you clearly had a specific person in mind when you started this thread. This thread wasn't titled, Why Do People Feed The Trolls.
Believe me, even if he doesn't post in this thread, he's following it. Do you think he'd miss it, particularly after someone pointed him to it? He's feeding on it.
This is your doing. It's your thread. It's troll food. Take your buck back.
