A thing to keep in mind: just because there is an "agent" card on someone, does not mean they were a snitch ("productive agent"). It is entirely possible that at least some cards were there to simply pad the numbers - to justify a handler's existence. At least some others are likely based on the KGB agent's noting someone down as a source as a means of blackmailing them ("I am not a snitch!" - "Funny, I have a file on you already. Wonder what your neighbors would think when we drop you off and thank you. Might as well cooperate..."). Because good luck proving a negative. I am a huge fan of transparency, but I would strongly argue that raw data, without context, in this instance, does not mean proper transparency is achieved.
