Right. It's my timing's fault. Sorry about that.
If you say that something someone innocently did brought unwanted attention to them, then, yes, it is blaming the victim. Again, I take the line "I am posting under a different ID" not as a challenge, but as a signal that they would not like to be identified in relation to the content being posted.
People would have that level of trust with the people here with whom they interact frequently. They may not all be faceless strangers. I know what several people who post here actually look like. I have had meals with them. I have gone to museums with them. I value their opinions.
They clearly do NOT trust the 80,000+ people with their identity, or else they would not have posted anonymously. However, they do trust those who know them well enough to figure it out will not reveal their identity. And, yes, someone else may figure it out who is not in that circle, but that just means that they might be mistaken about the information they choose to disseminate not being traceable. Does that mean that they need to have their privacy violated publicly, just because they made a mistake?
If I understand your contention correctly, no one should post anything that they want to be private on the Internet. Is that correct? I am starting from the fact that people do post information that is private on the Internet, and that this drive to unmask people who are doing what they can to protect their identities seems to me to be misguided. People have seen a value in getting help here. You can debate their wisdom in doing so, but it is a separate discussion.
