Something strange (hotlinking question I think) CAREFUL PLEASE

[Kinky]

BE CAREFUL/PROTECTED BEFORE CLICKING ANY LINKS IN THIS THREAD!!!!
I'm getting strange shit going on in my server stats... this russian site http://www.fn.com.ua/ is showing up in my stats and linking to one of my free sites at
http://www.fn.com.ua/free_pics/11/60...d_Nipples.html only with a bunch of russian ads around it

my site is http://yougetoff.com/girl_with_pierced_nipples/

when I click thru from my server stats to the site in question my hotlink protection seems to be working, but they have a text link that says "if you don't see the photos please click here" and when you click it everything shows up fine??? and there are still russina ads around it? WTF is this? is it a simple htaccess fix for me to block this stuff? any help or explanation would be appreciated

my sponsor codes haven't been changed but there is a homepage hijacking virus on that site and I would like to block the whole friggin' thing and not worry about it anymore if possible.... and this site is linking a ton of sites and galleries and from what I can tell it is a lot of stuff that gets listed at Tommy's as the description that Tommy's gave my site is also appearing on the hotlinked page and when I was checking stuff out there were a lot of Tommy's buttons on the sites/galleries
