How to remove your 4chan account

4chan does not use a registration system, so there is no account or profile to remove. To post anonymously, simply leave the [Name] field blank when submitting content.

Your IP address is visible only to site administrators and is not made public. If content about you was posted on 4chan, note that threads expire and are pruned automatically — most content disappears on its own within days. For archived copies on third-party sites, request removal from those archives directly or use Google's outdated content removal tool.
