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:
I made no changes to any of my posts or comments, though I haven't been particularly active on Reddit. It has been un-usable for a long time for me because it seemed like every time I tried to make an original, thoughtful post, it would get auto-deleted by a bot because I didn't include the correct "flair" or some other non-sensical bull, yet others could just spam those same subreddits with memes and nonsense without issue. I would comment occasionally, but that's about it.
It might be a good idea though to go through and check my comments to see if anything looks out of sorts or was edited without my permission.
I did a data request and then it took a while to receive my data, so I used power delete suite delete in case the API stopped working. Rewrote and deleted my comments.
In my file there was comments overwritten with the writing I had put in before it got deleted. It was gone but present in the data export. So seems it was at that time the data back up was done they were not deleted, but what was rewritten was present.
There were also comments and submissions that didn't get deleted by power delete suite even though I can't see them in my profile. So those I have to go through manually using the csv file to delete them. Trying to get shreddit working to automate that process.
