This is what the people at the internets want you to believe. Do you think it is just a coincidence that there are 7 layers.
True! The number 7 seems very important to the Free Masons! Just look at the measurements of the Statue of Liberty! In fact, it's an international conspiracy... And international organization determined that there were to be 7 layers, and IBM agreed, those corporate lackeys!
However, the cats that are actually within the tubes that make up the Internet have sabotaged them, and reduced the number to only 4 layers... Cats don't do international conspiracies that they're not in charge of!
