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.
Deleted all of my comments and posts manually. Didn’t delete my account, though, and I refuse to go back. It can flourish or die. I just don’t care about reddit any longer.
