OG Redditors, what are the darkest Reddit moments/threads that no longer exist or got lost over time?

Here is the post. The OP couldn't log back into her old email so she was never able to reach out to her. Her last response:

Hi - I just logged into this account again after a few months, sorry I didn't know there had been any new responses. No, I thought about it for a couple of weeks and even wrote up a letter to send but then decided not to...anyway that email account has been closed down for so long that when I tried to reactivate it I couldn't remember the exact username/password and nothing I tried worked...so she wouldn't have heard from me anyway, it's been close to 13 years now and I couldn't get into that email address.
