I'm pretty new here, so I might be sticking my head where it doesn't belong.... But in my mind, there are two things being balanced here. Some see anonymity as a way to "cool down" tense situations. Others see it as a mask behind which to hide. Is there any reason both can't be accomodated by having the borg-er revealed after some delay? So, perhaps a list of people borg'd and who they were borg'd by, or maybe just a /msg or something of that nature. By enforcing that delay period (6 hours, maybe, or 24?) it would give the person time to cool down, but avoid the "facelessness" that can arise.
That seems like a reasonable compromise, but maybe this is brutally hard to implement, or I'm missing some hidden gotcha?
