I’m a fully mobile user (Android), so that limits my options. I don’t just want to delete my account but also delete my posts and comments.
I was mostly shitposting but still had some 200k Karma so it could pinch Reddit a bit to remove that but it won’t hurt users or Google search since I wasn’t doing anything ‘productive’ or ‘helpful’.
You want Power Delete Suite. You can filter what you wish to delete by karma, gilding, subreddit, whatever. You can also batch-edit your posts rather than deleting if you want to leave a little message on the way out.
