Malicious agents can't make money on their services, since they only provide a very low value. So far we have studied what happens when an actor pick anyone , the closest seller, the cheapest seller, sticks to a favourite seller or to a locally recommended seller. We find that by disallowing buyers to choose from all sellers a larger number of seller agents can co-exist. This happens as the actors in regions infested by malicious actors go bankrupt, making the malicious actors go bankrupt too. All of this is very dependent on the migration level between the different regions.
High migration leading to an almost global environment is much more sensitive for bad agents.
