Especially if you have an old reddit account.

I have seen too many posts of users complaining about being permanned on their reddit accounts for flimsy reasons. Some of these users have account that are over 10 years old on reddit. If you make the decision to delete your reddit account, do the world a favour by deleting every activity you made on that account. I mean posts, comments, chats, picture uploads - take your time to clean up - 😉. This could take weeks depending on how much data you have amassed with that account, but in the end it is worth it.

If you simply delete your account, reddit holds onto these data. They will sell it, use it to train their AI models, basically using your effort for free after permanently denying you access to their services. Seeing how reddit is trending towards a bot-only outfit, even some moderators are bots, you do not want your data to contribute to that cesspool.

They can fingerprint all they want with data that does not exist. Good luck to them. Please play your part in dealing with the reddit bots/moderators that have found a way to steal your data from under your fingertips without you even knowing.
