What is dwtus.com? This is driving me crazy. My site has 1163 backlinks from dwtus.com. I can't find any reference to dwtus.com in any forums and whenever ever I go there the site appears to have a problem and never loads. I don't get any errors, it just never loads. Is a competitor attacking me with negative SEO? Can anyone share any insight to dwtus.com. All I know is it is Chinese.

Thank you for any insight you can provide.
