take a look at this:
http://www.google.com/search?as_q=co...h=&safe=images
someone maked a thousandth subdomains with others sites domain url in they titles and tags
so, when someone will search for domain.com the link domain.com030.com will be displayed in the resutls.. i think that's is a stealling of the domain.com google traffic..
is this legal?
