I would rather leave useful information where it is for anyone who needs it to find later. A lot of Reddit is on Archive.org and, like you said, their servers so I don’t really get what this accomplishes.

9 years backed up and scrapped already. If (when) nothing changes before 29th, last year will be backed up and overwritten with "Content removed. Restoration from backup will result to GDPR and RTBF complaints."

While I do understand, it's sad to see a lot of past content vanish without a trace. It's damaging to culture, and even though many posts might have been not that important, there will still be some information that is inevitably lost. What would be great, in my opinion, is being able to back posts up to another place, so that they get preserved outside of Reddit.

I am really conflicted on this. I agree in principal that Reddit shouldn't benefit from my years of comments and posts, but I can't count on how many times I have searched for something and found an old Reddit post or comment that was just what I needed.

Most of my Reddit comments or posts are probably not very useful, but some of it might be and I am not against other random people can find and read what I have written through the years. Reddit as a whole is a vast collection of good advice and insight that is valuable to preserve. Sure it might be archived on archive.org but that is hardly searchable for most people.
