Looking this thread growing it appears to me, that at least one thing 
becomes evident here:

Xah unwillingness to learn from the bad past experience contaminates 
others (who are still posting to his trolling threads).

Here another try to rescue these ones who are just virgin enough not to 
know what I am speaking about:

Citation from http://www.xahlee.org/Netiquette_dir/_/art_trolling.html :
"""
What I want this document to focus on is how to create entertaining 
trolls. I have drawn on the expertise of the writer's of some of 
Usenet's finest and best remembered trolls. Trolls are for fun. The 
object of recreational trolling is to sit back and laugh at all those 
gullible idiots that will believe *anything*.
[...]
Section 5    Know Your Audience
Remember that you have two audiences. The people who are going to get 
the maximum enjoyment out of your post are other trollers. You need to 
keep in contact with them through both your troll itself and the way you 
direct its effect. It is trollers that you are trying to entertain so be 
creative - trollers don't just want a laugh from you they want to see 
good trolls so that they can also learn how to improve their own in the 
never ending search for the perfect troll.
[...]
Section 6    Following-Up
Try not to follow-up to your own troll. The troll itself quickly becomes
forgotten in the chaos and if you just sit back you can avoid being 
blamed for causing it. Remember, if you do follow up you are talking to 
an idiot. Treat them with the ill-respect they deserve.

being the audience)
