@dumples OH, that's great! How did you do that? I would like to archive my comments too, if there is an easy way. Is there some tool for mass downloading (and probably deleting?).
They most-likely used a Reddit Data Request. It’s kind of like Google Takeout if you’ve ever used that. If you’ve already deleted your reddit account it won’t work IIRC. I scrubbed my comments and posts with PowerDeleteSuite a day or two after I submitted the data request, but before I actually revived the data (took 20 days), but all of my comments and posts did show up in the data request. Don’t know if that points to reddit actually keeping that data in their database and just hiding it on the site or not, but either way, if it’s not visible on the site it becomes worthless to them unless they decide to provide that data to someone behind the scenes.
@sneakyninjapants I know some people complained that Reddit would reinstate all comments that was deleted by hand, every single one. So if you delete your account, maybe Reddit will bring the comments back after some time. I didn't delete my account so far, only logged out and not logged in since. As I'm in the EU, Reddit probably has to provide such an option to download and delete my comments, but I'm not sure. Not going to log in for the moment. I will have this in mind though, thanks for point it out.
