• I am not a expert or a lawyer, but I believe user actually hold the right to completely erase personal data:

      The data subject shall have the right to obtain from the controller the erasure of personal data concerning him or her without undue delay and the controller shall have the obligation to erase personal data without undue delay

        • Technically, they could retain posts from users if they are irreversibly anonymized. However, ensuring with 100% certainty that none of your posts ever contained any personal data that could lead to the identification of you as an individual is challenging. The safest option is therefore to also delete your posts.
