You are not legally required to complete work for any of the proposals you send that are approved, but we do strongly recommend doing your best to finish any campaign you're approved for, as backing out of or not completing the work for a proposal after it's been approved would be a poor experience for the brand that hired you.
We want to make sure everyone is happy with their experience using Podcorn, and we appreciate your help with this mission. If you have a poor experience on Podcorn, please let us know! We'll do our best to help.
