You are making yourself look stupid, Don't drag down to his pathetic level. Keep it on-topic and ignore the troll, His posts will be removed so you can keep in on-topic but your posts will remain up and make you look stupid making you look like talking to a wall.
Blacklist, Ignore and move on with the topic.
I mailed the thread creator about this, Though I think this is advice to all thread makers and this should be known for future references so I decided to paste it here.
Now there's moderation! (yes my friends)
