DPR, by no means am I stating that the invite system is a poor decision. As I told Synergy, it is a very effective way at deterring spammers/trolls and is a solution that is much more favorable than closing off registration completely. I am also not "criticizing the system no matter what the state". As a whole, you guys are doing an outstanding job of delivering on market features while maintaining a positive forum atmosphere. You state yourself that the tracking of invites poses the threat of being able to form "a web of people". That is the negative part of this functionality. What I have yet to hear is what the positive side is of having a user being able to see who invited them. It is one thing for the administrator to see that information so as to further deter spamming and such, but allowing users to have that visibility to their own inviter serves no purpose that I can think of.
