I don't see how giving authors more advertisement for their stuff is a bad thing. Simply put, I'm sure if asked the staff would be happy to remove any files that people don't want hosted.
However I would like to state that from what I've seen on the boards, here and other places. No one has stated anything about 'copyrights' or 'permission' about their stuff, while yes I understand its common curitsy to abide by unwritten rules and laws. I don't really see how this site is any different then that of say a musem for the english community. To me, labeling a site like this looks bad on you, not only that but to bring an uproar about something like this will cause the community to split, do we really want to do that to a game that has barely been out more then what, 2 weeks thus far?
To me this is just a cry for attention.
