I tried a Chrome plugin that had the limitation of 50 comments / posts a day but required money to do more. I had the day off, so I ended up doing it manually. Was a real trip seeing all the comments and stuff I’d forgotten about from all those years ago when Reddit was still a cool place and people were mostly cool.
Clone your drive first and then no matter what happens you have a quick click to restore. I’ve run dual boots on multiple distros for years and you learn a whole lot when things go wrong.
