Is this a violation of the rules and should such posts be deleted?
In general, we consider doxxing to be
linking of a pseudonymous identity with a real-life identity:
Personal information is defined as anything which links a user's online identity (username, email, etc.) to their meatspace identity, excluding links that the person himself has posted.
If that ID was claimed to belong to some forum member, then that'd be doxxing. But because it stands alone, we don't consider it doxxing.
Separately, it's not allowed to post things that are especially security-sensitive:
anything that the legacy insecure government/banking system requires to be secret is not allowed anywhere. This includes social security numbers, credit card numbers, and certain account numbers.
If those images contain info which would be very useful in stealing that person's identity or committing similar fraud, then perhaps they should not be allowed under this rule. I don't
think they contain such info, though I'm not 100% sure.
Also separately, if info about some person is posted with the implication that some sort of violence should be committed against them, then that would not be allowed because incitement isn't allowed. For example, this would be too much like incitement: "Here's a bad person's photo. Maybe someone should do something about them." I read (via Google Translate) light_warrior's post as (disappointingly)
hateful, but I don't read it as incitement.
So I don't think that the post should be deleted.
