Hello. squidGuard included URL Blacklist. This list license is not find, and copyright infomation is not find. And, Blacklist is contain illegal domain and URL. (I think) Is this is legal ? I think that it is illegal, legal problematic. NOTE: I am not a legal professional. And I think that this is non-free. I suggest that resolve legal problem. Thanks.
It's a list of websites. I doubt such a thing is copyrightable. Also, while the content on those websites might be illegal or morally questionable, we're not distributing the content of those websites, just a list of URLs.
