Oda said that Absalom was at Marineford too so we take that as meaning he saved Moriah. It was said in SBS 71

"D: In Chapter 700 there is a reporter named "Absa", that's referring to Absalom right? Right? And if you look closely, there's even the pirate ship. What other kinds of eroti… amazing articles... What other kinds of eroti... I mean, moving articles... What other kinds of erotic articles does he write? P.N. Makino♡LOVE
O: Yes, that is Absalom. How nostalgic. In fact, he was also at the Battle of Marineford. After the battle, Doflamingo stated that something strange happened to Moriah. I wonder why? Perona is also worried. Did Moriah really die? The only thing that I can reveal right now is Absalom, going by the name "Absa", has been reporting a lot of big news using his Suke Suke no Mi; this is true. He can take many interesting photographs with that ability. His articles are very popular right now. [/hide] So no dumb prediction there :)
To be on topic= The REAL reason why Absalom likes to hide invisible and peep on women is that he wants a gender change operation and he is doing research on how to act like a real woman.
