I sympathize with AK, but it's their responsibility. But that's exactly what it was created for.
One says "they agreed," the other says "no," and both confirm it with logs. It's easy to point a finger and say, "you said/did it wrong," but how should it be done correctly? Everyone has high and pure moral principles, but we won't even bother reading the logs; let someone else deal with it, and we'll criticize them afterward.
