The key terms in every contract:
90 day paid license: you can run the content as a Partnership or Whitelisting ad for 90 days
180 day organic license: you can share the content on your own channels for 180 days
Optional posts: public posting is optional for the creator, but the content itself is always produced, delivered, and licensed to you. You can run it as an ad regardless of whether the creator posts organically
For required posts the usage term starts when the creator publishes; for optional posts it starts at the moment of approval. For paid performance we recommend optional: a broader creator pool and a lower cost per post.
