Puff locked your thread, because there are already many threads on that subject. And I am sorry to disappoint you, but the admins and mods decide if a post needs to be locked, not the original poster. You as the thread starter can only ask the mods or admins to lock your post if you think that's necessary. Double posts will be locked and so will posts that are only meant to discredit other forums or people. Yours was a triple post, that is why it was locked.
I hope I answered your question and I will lock this thread as well, since you now have your answer. I will also move it to the forum faq section. If you have any questions, you can contact one of the admins or mods by pm.
