The situation as you set it out is complicated, and unfortunately happens too often when people have creative works made for them. If you have someone create something for you, if you want to own the rights in it you must have a written agreement or else the creator must have created it as your employee. First, did your friend have a written agreement from every creator that he/she would own the rights in the website? If not, then your friend only had a license to use the creation and can't stop any of the creators from doing anything they want with the work they did. Given the complexity of the facts you state, you would have to sit down with someone well versed in intellectual property to go over this because they almost certainly will need to ask additional questions.
