No, taking the piss is not learning from what you did wrong.
When I delete a thread for not sticking to the rules, I always do a so called soft delete. This means that the reason it was deleted is visible and I can even make the thread magically re-appear.
Only a very few people have bothered contacting me, asking what went wrong, and I have given them all an explanation as to why they're threads were axed. These people learned from it and got it right the second time round.
However, many people just go "f*ck, my thread got axe, so I must have done something wrong. Never mind, I'll just post the exact same thing again." Quelle surprise, the second thread gets the chop too. If you don't know what you did wrong, just ask...
Oh, and I don't see any reason to kill this thread. I did however move it to a more fitting part of the forum.
