Friends I had a domain very similar to world most brand(non commercial) name. I had started a similar project exactly free / not for profit Neither I stole any logo, content,database, etc but concept and theme(website theme) is same is almost same I have put a line (neither we nor original website have no co relations) Is this legal ? Thanks in Advance.
It depends on the actual name, but it sounds like it could be trademark infringement and a disclaimer will not make it go away.
