This is one of those situations in freelancing that stings even when you know it is technically part of the arrangement. Some clients take the work you produced and present it to their audience or their own clients without any mention of who actually made it. In some cases it is covered by the contract, but the feeling of watching your work get credited to someone else is still something many freelancers find hard to sit with. It raises questions about credit, ownership, and what you actually agreed to. Have you ever seen your work presented publicly as if someone else was behind it?
