Hate to break it to you, but the time to do that was over a year ago, and even then it wasn’t ever really a sure thing - we don’t really know what their backup policies are around that stuff.
This is what the former power user community that made an exodus from Reddit roughly a year ago has been trying to communicate, but a ton of people here seem to enjoy keeping their toes in the water over there, with rather predictable consequences (literally, the post we’re commenting on).
All that said: I am very much looking forward to the absolutely titanic lawsuit around GDPR I’m sure is in the works over this.
Wish I had known this beforehand in like several accounts I've had with that shit-ass place.
Then again, it's likely that Reddit has shit archived because Spez is one of them data-farmers like Mark is. Nothing is truly deleted from their sites. It's just archived.
There's been lots of evidence that proves this, because people have dug up old comments, even down to who posted it originally. Then, even if your account is deleted, your comment body is still there, I know because I've deleted an account and checked back where I was before.
