This is similar to when I heard reddit was doing the API lockdown, I wrote an automation bot over the weekend that self-destructed my subreddit and the entire post history. The bot also automatically downloaded and archived all of the content on my local machine.
It was annoying because at first I couldn't get access to older posts since at the time reddit had changed their API to only show the first X posts (100 or 1,000 or whatever). So I told my bot to delete the posts as it archived them so as I deleted content, reddit had no choice but to populate the page with the older posts.
And that's how I archived my subreddit. Reddit banned me two days later for automation, lol. I did not break any of the reddit or reddit api ToS during this process but I guess I upset someone.
