Is Nucleus supporting terrorist organizations?

No, there's no need to start sending hate-mail. While it's true that there's at least one terrorist site that has chosen Nucleus to power its website, there's nothing we can do to prevent that. The GNU GPL license under which Nucleus has been released, allows anyone (anyone!) to download and install it for free. Even terrorists.

To make things clear: We're not supporting these terrorists or any other extremist organization. We've never had any contacts with their militants and are not providing hosting/whatever for them.
