Huh? But, you see, we don't use the search engine.
>www.hotelsbrazil.com has it's own URL, i.e. its not an extension of hotelscentral (hotelscentral.com/hotelsbrazil).
This is absolute nonsense. What possible principal of logic or website design could a website from extending across multiple domains? And how could it possibly overrule the observed fact that MANY sites, including this one, have spread themselves out over multiple domains (often out of a misguided belief that it will help them in the search engines?)
>However if it violates the rules, I would like you to remove hotelscentral.com from DMOZ and then include all our country sites into DMOZ.
What you request is, as you can see by reading the submittal policies, the most serious violation you can commit, and the one that will cause you most damage. If you persist in this, we WILL remove hotelscentral.com, and (as the guidelines state) all other sites related either to it or to you.
We take this issue seriously. Don't try to push editors around on it. It WILL be counterproductive.
