It took a while but I finally got my Reddit data export
It took several weeks but I finally got my Reddit data export for my account. If it wasn't already obvious, the direct messages there are not encrypted in any meaningful way. One interesting variable I found was in the file named "statistics", there's a variable named "is_deleted" which is set to false. This makes me wonder if, when you "delete" your account, they just flip this variable to disable login but still retain all of your user data. The file names are pretty self explanatory on what they contain, but the if you're curious, the files in the export are:
Yeah my whole export was only like 3MB of CSV files, so I'm guessing that any media you upload just gets dumped into a giant bucket with everybody else's stuff and then referenced by your post or whatever. Kinda makes you wonder if that stuff gets deleted if you delete your account.
