Pinoy Big Blogger asks the question: Pinoy Big Brother Infiltrated by PeP.Ph Staff?
First of all, PEP is a joint venture of Yes! and ABS-CBN's mortal enemy GMA, so it is interesting that PEP announced their "list" before ABS-CBN. Secondly, the clues were so vague it could only have been a leak. "Despised Babe" could have been anyone and the fact that it described a non-star could only mean inside information.
Good job Retzwerx!
