A few weeks ago I submitted a request to Reddit for a copy of my data. In the meantime I got bored of waiting and deleted my account. I thought I would not receive my data, but yesterday I woke up to an email with a link to a file with all my data in!
So to all those who are waiting to receive your data before deleting your account, as long as you have a verified email address associated with your account, you can go ahead and delete your account and you’ll still receive your data!
This happened to me as well, https://kbin.social/m/RedditMigration/t/173304/reddit-data-retrieval-thoughts
