In the very bottom of http://www.atlnightspots.com there is a link that says protected by (muslim words) <font style="font-size: 9pt;text-decoration: none;" color="#C0C0C0">صور اطفال</font>
I used the TAC plugin and it didn't even detect it,Securi doesn't come up as malware but when I am on my iphone my site gets redirected to porn sites I suspect its coming from that link.
