Just my prediction. An example in my mind was an interaction between a state (represented by some person) and individual: e.g. if you are entitled to receive a support in unemployment, you will get it, even if the common sense makes it obvious that you are just abusing the rules; as long as you pretend to follow them.

This is open to interpretation, but my understanding is: "help unemployed people" = cooperate, "let them die" = defect; "inform truthfully about your employment" = cooperate, "falsely pretend to be unemployed (while making money illegally)" = defect.

I suppose there are more examples like that, which could be generalized that a state (or other big organization) becomes a CooperateBot when trying to achieve a win/win situation, and is abused later.
