Depop is a social media app that is popular with young people. It is a place where people can buy and sell clothes, accessories, and other items. When a seller is "restricted," it means that their account has been temporarily suspended because they have violated the terms of service. The most common reason for being restricted is posting copyrighted material without permission. Other reasons include listing prohibited items or violating community guidelines. If your account is restricted, you will need to contact Depop Support to find out why and what you can do to have your account reinstated.
