Where is my last thread?

I just asked the quickest way for leveling.

Yeah, I have seen that. And two days ago it was "Post:16"

Were all your 15 posts in that same thread, and did the thread take a turn for the worse in terms of people, whether yourself or others, bickering? If an entire thread gets deleted, then that could be the cause of your missing posts and doesn't necessitate that you personally did anything wrong.
