Lemmy is like Reddit and here because it has threaded comment discussions.

It's also federated, so you can pick a server you like and have discussions with users from various servers together.

It is. That said, doesn’t CCPA require them to wipe personally identifiable information after 30 days (i.e. logs)? Logs are interesting because typically they’re stored in write-once read-many type of data stores. In reality this means, most companies will just decide to wipe it to comply. They may, and probably do store anonymized data but if that can be traced back to a specific user technically they’d be breaking the law.
