Why YSK: Because you may delete your account and find your comments and other content is restored and beyond your control.
DO NOT DELETE YOUR ACCOUNT YET.
Keep overwriting your comments over and over so they cannot just roll them back a single edit.
I prefer Power Delete Suite as it does not need authorization and just uses the website through your own browser. I will continue to overwrite my comments on repeat until the API changes.
Just goes to show how a GDPR like law should be enforced in all countries. If you can’t edit or delete your own content, it certainly infringes on your rights.
Here in the US we only pretend to have rights until conservative Supreme Court majorities say we never had them to begin with.
