Free-riding is the biggest challenge to any P2P scheme. It inhibits effective machine functioning. As a consequence, several researchers suggested many methods to counteract the impact of free-riding in a P2P or network. We suggested the PPM mechanism here, which can prove very useful in this regard. This paper also suggests the blacklisting approach, which may also be helpful in mitigating free-riding behaviour. In our work, behaviour aspect is the most significant parameter to analyse free-riders' behaviour. The methodology we used here monitors the free-riding interaction and allows peers to be in the network. It forces colleagues to contribute rather than customers. Our work improves on several past methods. The findings reveal that the amount of free-riders in the network reduces as the number of nodes grows. It also shows that behaviour factor is implicitly proportional to blacklist counter, i.e., if a node's behaviour factor rises, the blacklist counter decreases and vice-versa. Future, we should introduce other mechanisms that might will the likelihood of blacklisted peers. Ultimately, this would entail a decrease in network free riding. This would also contribute to decreased server load. Our paper may be liberated from the central server concept. We should also try to increase the degree of collaboration among network peers so peers can function more together in the network. We may also enhance the network's protection aspect. Extensive system simulation may be performed to see its success in large-scale network.
