Works great, perfectly determined which people in my workplace are programmers and which are biologists (by giving them a different color). Could one subvert the graph building with the following? Construct an email address A1 that will forward emails to you from person B. Likewise, you communicate with B through their B1. After a period of time (or n messages), switch the pass through entity to a different email address A2 and make a rule on the mail server to bounce the emails from B if they try to reach you at A1. Keep using A1 with someone else.
