So, you wanna know what his emails say?
The Rh (Rhesus) blood group system (including the Rh factor) is one of the currently 30 human blood group systems. It is clinically the most important blood group system after ABO. The Rh blood group system currently consists of 50 defined blood-group antigens, among which the 5 antigens D, C, c, E, and e are the most important ones. The commonly-used terms Rh factor, Rh positive and Rh negative refer to the D antigen only. Besides its role in blood transfusion, the Rh blood group system, in particular the D antigen, is a relevant cause of the hemolytic disease of the newborn or erythroblastosis fetalis for which prevention is key.

Can you explain what the difference between a thread which is simply removed, and one for which additional steps are taken to remove all history and traces of the thread, including the thread vanishing from one's recent posts? I have seen the former many times, but the latter only once, and I would like to know what grounds are necessary to trigger this extra level of extreme moderation. Thank you.
