How to block a russian site from my blogspot - cjsc er-telecom company samara

Anyone, looking for help. About the fact that every day I have about 10 hits from Russia on my free blog "Blogspot". The site from which they are contacting is blackhatworth.com, the provider is cjsc er-telecom company samara and the city of origin is Samara. Also the site uses Amazon links.

Thanks, Joe
