I sanitized all of my comments before I deleted them. They’re welcome to bring them back. it’s all just a protest message anyway. But for those who didn’t, this is really shitty.
they don't retain comment edit history. they literally don't possess this capability-- it's a GDPR requirement.
it's possible that some of your comments were missed when you tried to sanitize them. i ran into this issue myself and had to re-run the sanitization script a few times to get all of my comments.
