hello every one and sorry for bad language.
today i have big problem and i think it is about spam or hack.
my site for example is ccc.com and it show on other domains, for example a.qwe.org without my Permit.
my problem : admin of qwe.org think i hack his site and put my site (ccc.com) to his sub domain.
my question is how i can block any domains to show my site on their sub domains ?
