The owner in question is Stephane Pacaud. Do not try contacting him through any of his e-mails listed in the WhoIs records. It is a possiblity that his gmail e-mails (nophest@gmail.com &
xnxxdomains@gmail.com) were stolen and compromised. He owns several high profile websites like xnxx.com, y8.com, pog.com, ant.com, etc.
He has told me that many of the domains have been retrieved and placed on lock. I tried calling him and he's not picking up. So if anyone has any questions, I'll try my best to answer on his behalf.
