Not to devalue privacy (at all), but if the GDPR is so far reaching that anonymous posts are expected to comply with this, that destroys much discussion. Don't see why that's a reasonable expectation. That's no longer private but public data.

If you contribute to public knowledge/discussion, then taking your ball and going home leaves huge gaps in history, the same way you see [deleted] throughout many Reddit threads.

Is the GDPR that far reaching?
