I have a client who is asking me to make revisions on a book cover project she had done with a different Fiverr seller. She’s tried several times to get in touch with her original Fiverr person, but they have not returned her messages. This client is on a deadline, so I’d like to help her, but I want to ensure that I can legally make the changes to her project without infringing on any copyright issues. The client does intend to acknowledge both of our efforts once the project is done. The question boils down to, is it allowed/legal by Fiverr standards to make edits to a different seller’s projects?
