xuk.ru is a site to avoid completely.
First, they run a script which adds their logo onto the picture sets which are stolen from other sites. They cannot blame members for posting copyrighted material, as their own logo is on the material itself. Right now xuk.ru is a prime target for the copyright cops and protection companies working for met-art, femjoy, justteensite, amourangels, ftv and half a dozen more major sites.
Second, they run scripts which will attempt to install adware worms on your PC. Obviously, if your defences are state of the art, then they will be blocked. But be aware... the most malicious trojans are built in russia (and china and india), and the US-based anti-virus and anti-malware software updates are per definition out-dated when released.
