Looking at the source code of their site, what they appear to have done is take a complete copy of your site using a product called Teleport (you can tell they used Teleport because of all the tppabs tags in the html code). This means that they're not linking directly back to any of the graphics on your site (or at least not to those I checked), so they aren't relying on leeching, so anti-leeching techniques won't help.
If you've used a standard template as T suggests then there's not much you could do legally about them grabbing your look and feel. You could almost certainly sue over the appropriation of your logos, but how much is it going to cost you to bring an action in Russia? Your best action is probably (1) to send an email asking him (domain: ART108.RU, person: Igor V Shavkunov, phone: +7 905 7647569, e-mail:
v_p_d@mail.ru, created: 2004.01.09) to stop (which you've done), (2) if no response, I suggest contacting the hosting company that is hosting the page for him. By doing a DNS lookup and then a whois on the alias, that is rbc.ru, whose email address is
hosting@rbc.ru. If you email them giving the details and asking them to ensure that the stolen material is taken down then they may very well close down the offending site (or they may not, but it's worth a try)
For the future, to stop someone else doing this to your site, you may want to look into products such as
HTMLProtector which can stop Teleport and similar products grabbing your site.
