Bitcointalk.org aims to enable as much freedom for its users as is legally possible. We will not remove content just because it annoys you. In particular, under section 230 of the Communications Decency Act, bitcointalk.org cannot be held responsible for defamation by users, even if notified that possible defamation exists.
If you send us legally-nonsensical demands, we may publish them to make it clear to the world that you are illegitimately and possibly-illegally attempting to stifle discussion.
