Now everyone just needs to send their email addresses to HIBP, i.e., email HIBP, so he can connect these identities with IP addresses and working email accounts. For peoples' protection of course.

As expected, HN commenters will not like this viewpoint as they may themselves be trying to profit from such intermediation and the data collection it enables. They may have even convinced themselves they are doing good.
