It seems that this community views anonymity as a sacred right, and discovering the real identity of ("doxxing") of someone as a mortal sin.  Sorry, I don't buy that.

While it may be OK for people to use pseudonyms, it is also OK for people to blow them.  In any significant personal interaction each party has the right to know the identity of the other.  In commercial business, in particular, it is foolish to make a deal without knowing the other party's real name and photo, and the address where the police can be sent to; and without checking his professional history and legal record.  That applies not only to the principals of companies, but also to key employees.  The "right to dox" also applies to anyone who accuses or insults someone.   

In particular, I think it is quite appropriate for BFL clients to try to uncover the identity of the "SLoK" who managed the BFL forum (under a deal that has not been clarified) and may hold assets that should be surrendered to the receiver.
