They've stated that's exactly what they're doing in several pieces.
> It's not "mistake" if PII is revealed in every single release. There are dozens of other organizations that have strong records on this. wikileaks is not one of them.
Likely because those "dozens of other organizations" don't publish many leaks and especially not in anything approaching raw form - every single leak I've seen in a major paper has been heavily filtered down and distilled into a specific narrative. WikiLeaks just publishes with minimal editing - any narrative from them is completely separated from the leaks. That rawness is what makes them better than other approaches for getting real information out, but it's also what makes them worse at censoring that information.
