I have found one of my videos being used without my permission on an online auction site. I don't mind people viewing my videos and sharing the link to it among friends or even embedding it in discussion forums where others might enjoy it or be inspired from it. However I DO NOT want others to use it in a commercial venture without my permission. Is there a way to allow domain blocking rather than Domain Level Privacy in Vimeo Plus? I would like to have the opportunity to block the use of my video in certain sites (ie: ebay) but allow it to be used on any other sites. This is the opposite of the domain level privacy but I feel it would allow maximum exposure without unauthorized use.
