I do wonder how much backup data a site like Reddit keeps. I suspect their back ups are poor as the main focus is staying live and moving forward.
I'd imagine ability to revert a few days, maybe weeks but not much more than that? Would they see the value in keeping copies of every edit and a every deleted post? Would someone building the website even bother to build that functionality.
Also for reddit so much of their content is based around weblinks, which give the discussions context and meaning. I bet there are an awful lot of dead links in reddit and their moves to host their own pictures and videos was probably too late. Big hosting sites have disappeared over time or deleted content, or locked down content from AI farming.
The more I think about it, they were lucky to get $60m/year.
