seocleark and listingdock what are they up to

i notice new seoclrk ad campaign all over internet directing back to linking dock but its a mirror of seocleark wouldnt that be bad for seo since it not sending people to seoclrk directly and in terms of seo wouldnt it be counted as dublicate content am kinda curios what they are doing since i never sign up on listning docks but i can login with my seoclrk details
