There's no "mystery" behind why it got removed. Suchmoon already explained it to you.
It's you spamming the forum and the trust system with useless garbage. And using threads posted by a known troll as references, so they disappear when the troll gets nuked. Create your own threads and archive them.
The person who wrote the thread you referenced was evading a ban for spamming. They got caught and their posts were deleted. Basically, you were relying on the words of a banned spammer to make your point. Congratulations.
