• I’m not familiar with the details of the CCPA, but AFAIK under GDPR you need to actually request the deletion of data by invoking article 17. Just going through your account and deleting posts is not the same thing.

      Also, this only applies to “personal data”. You’d probably need to ask a lawyer if posts on reddit can be deemed to be personal data on principle, but IMO as long as the posts don’t contain any personal identifiable data themselves, it should be enough to remove the username linked to the data like reddit is currently doing if you delete your account. The data would then no longer be linked to an individual and therefore would no longer be personal data.

      IANAL, this is just my personal interpretation and I might very well be wrong.
