I left mine because there's lots of good info out there that will help people some day, but I'm done posting anymore on there. All my new comments go here.
I actually would recommend deleting. Whatever commercialized AI reddit has cooking up is just going to be trained on your words and information, if it hasn't already happened.
They'll just use archived versions instead then. It's not like you have even a smidge of a chance to find out, so who cares about legal issues or or your right for privacy.
I propose that a new subreddit be created where you post something like "please ban me" and then people who visit will go and report you for sexual abusive and hate speech so you can get your account locked and banned site wide. Maybe there's already a thing like that?
