HaLeiVi,
I agree that the scenario I described is not a likely vector to obtain someone’s identity (but not an impossible one). I was working with the object lesson that YW Moderator-42 set up.
Would you agree, however, that there are more likely scenarios where CR users can ascertain the identities of other posters? It has happened several times, such as when cantoresq’s niece figured out who he was (which was benign), or when mosherose allegedly harassed WolfishMusings in real life, because he gave very specific details about a shiur he was attending (certainly not benign).
I am not promoting or agreeing with hysterical suggestions to sacrifice the free flow of posts in the CR on the altar of security such as verified screennames or the like, but I strongly agree with the words of caution, which weren’t excessive. I was also surprised by the posters who objected to even that (claiming it disrupted the flow of threads).
