Published on 17 May 2025 in a thread the researcher opened with "Lets play a profile picture game! Here are a few fun DPRK ITW/remote worker profile pics and their associated emails." Each post in it pairs one address with the profile photograph used alongside it. This entry is one such post: the address kazuhirosasaki0805@gmail.com and the picture below it. The photograph is mirrored here because these posts are the only published record of the face an operator presented, and the accounts they came from are routinely deleted. It is not evidence of who operates the address: a profile picture in this dataset is as likely to be generated, stock, or taken from an uninvolved person. The name is this site reading the address, not a name the researcher gave: the post pairs an address with a picture and attributes neither to anybody.
