I'd have to agree with Desparate Andy here....while if an accusation is made proof of ownership by the accuser should be provided first before any action is taken by the sponsor...of course if proof is providen than a license for the photos should be provided by the webmaster to save their hides =)
I know I'd be pissed if a sponsor threatened to close my account if someone accused me of content stealing with no proof...I have licenses to prove usability of all my photos but I have enough work in a day to do
