I am sorry. I got tired and have not read pages 20-50. I am sorry if I am not up to everything in my understanding that
the problem currently of not having any info where master-p lives makes it impossible to start any legal action against him.
But even in the case if he is a minor there is a clean and morally 100% acceptable way to get forward and out of this situation.

1) TECSHARE posts publicly which police station is closest to the place where master-p lives
2) TECSHARE phones that police station and tells them the master-p doxx info.
3) All the parties that have been scammed out money also phone that police station and file a claim
4) the police start their work investigating the fraud and the wheels of justice begin their grinding
5) the scammed people might get their moneys back because the added pressure of police knocking on the door might make the whatever technical problems master-p is having mysteriously disappear.

All steps 100% moral and kosher even if master-p is a minor or one-legged dwarf or whatever.
