Look for the word "prostitutki". If you find one, I'll bet you find many more.
Yes it is there and lot of others also. I find that is Referer Log spam. The best option is to just avoid them and not click or display them on the site. Also it was advised by wikipedia "A simple attempt at rendering this form of spam ineffective is to prevent the search engine spiders from crawling the site logs by moving them to a non-public area such as a password-protected area, by using a robot exclusion file, or by appending the nofollow value to the links" How its going to be implemented i have no idea, also google mentioned that these log spams doesn't harm your rankings.
