You’re right, Fiverr’s TOS speaks about it.
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).
By purchasing a Commercial Rights (Buy-Out) with your order, in addition to the basic rights, the Seller grants you with a license to use the Voice Over for any corporate, promotional and non-broadcast purposes. Corporate, promotional and non-broadcast purposes means any business related use for the creation of, or to promote a for-product profit or service (with the exception of paid marketing channels), such as (by way of example): explainer videos posted to company websites, social networks or email campaigns, audiobooks, podcast intros, and strictly excludes any illegal, immoral or defamatory purpose.
By purchasing a Full Broadcast Rights (Buy-Out) with your order, in addition to the Commercial Rights, the Seller grants you with a license for full broadcasting, which includes internet, radio, and TV “paid channels” including (by way of example): television commercials, radio commercials, internet radio, and music/video streaming platforms, and strictly excludes any illegal, immoral or defamatory purpose.
This Buy-Out is subject to Fiverr’s Terms of Service. There is no warranty, express or implied, with the purchase of this delivery, including with respect to fitness for a particular purpose. Neither the Seller nor Fiverr will be liable for any claims, or incidental, consequential or other damages arising out of this license, the delivery or your use of the delivery.
As for the rest of us:
Ownership and limitations**: Unless clearly stated otherwise on the seller’s Gig page/description, when the work is delivered, and subject to payment, the buyer is granted all intellectual property rights**, including but not limited to, copyrights for the work delivered from the seller, and the seller waives any and all moral rights therein. The delivered work shall be considered work-for-hire under the U.S. Copyright Act. In the event the delivered work does not meet the requirements of work-for-hire or when US Copyright Act does not apply, the seller expressly agrees to assign to buyer the copyright in the delivered work. All transfer and assignment of intellectual property to buyer shall be subject to full payment for the Gig and the delivery may not be used if payment is cancelled for any reason. For removal of doubt, in custom created work (such as art work, design work, report generation etc.), the delivered work shall be the exclusive property of buyer, and seller assigns all rights, title and interest in the delivered work. Some Gigs (including for custom created work) charge additional payments (through Gig Extras) for a Commercial Use License. This means that if you purchase the Gig for personal use, you will own all rights you require for such use, and will not need the Commercial Use License. If you intend to use it for any charge or other consideration, or for any purpose that is directly or indirectly in connection with any business, or other undertaking intended for profit, you will need to buy the Commercial Use License through a Gig Extra and will have broader rights that cover your business use.
Frankly, I don’t understand why VO artists are under different standards than the rest of us.
Besides, as TOS puts it:
Fiverr does not check user uploaded/created content for appropriateness, violations of copyright, trademarks, other rights or violations. We invite everyone to report violations together with proof of ownership as appropriate. Reported violating content may be removed or disabled.
