This is the second time this has happened. I delete all my old posts and comments using PowerDeleteSuite. I view my profile - everything selected is gone. A few months later, it’s all back. I repeat the process, verifying it’s all gone. I log in today, months later, and it’s back. Simply maddening.
Is there anything I can do to make it stick?
If you live in the EU maybe requesting full deletion of your account helps.
Unfortunately, they have no obligation to remove individual posts/comments unless they contain personally identifying information (iirc).
This is only partially true - all comments include identifying information as they are always linked to a IP and username (both being personal information) and might be linked to a post history,etc.
In theory they could absolutely scrub that information AND make sure that none of your post holds your (or other peoples) persknal information - but they would need to do so manually and by someone who is quite knowledgeable in these matters. So while it’s possible it’s not economical to do so.
Currently Reddit usually does nothing and does not give a fuck, but that will fuck them over at some point - I know of multiple national data security ombudsmen who are currently investigating.
