Do they for all verticals, or are voice-over services simply framed in more detail within the ToS, @newsmike, @smashradio?
According to Fiverr's ToS, "When purchasing a Voice Over Gig, the Seller grants you a perpetual, exclusive, non-transferable, worldwide license to use the purchased Voice Over (except for commercials, radio, television and internet commercial spots)."
Is there a practicing attorney present who can clarify the legal interpretation of non-transferable in the above context?
