Decision: you can withdraw your comment at any time, even after people reply. A placeholder stays in the thread and your name will be removed.
Why: comments are part of the scientific record. Deleting one would leave replies without the comment they respond to. Withdrawal gives you control over what you contributed while keeping the thread readable. It follows the same principle as our account deletion guidelines.
