I don't get it...
Posters start their outing post with 'name changed for this in case friend/mil/DD/etc is on MN'. They then proceed to describe the entire situation, with specific details, but in theory nothing 'outing'.
Surely if said person is on MN and currently going through the scenario mentioned, it should not be too hard to spot that said scenario has been posted about. All the poster has achieved is not enabling their friend/mil/DD to identify any previous MN posts/replies they have made about other situations not involving them.
Do posters generally understand that notwithstanding the name change the other protagonist can still identify themself in the posted scenario and can still read all of the OPs opinion about it? Or is 'name changed for this' generally understood to be some sort of magic invisibility cloak that prevents certain other people in your life from reading your opinion of them on MN?
Am I missing something?
