Network nodes that are equipped to recognize suspicious activity may deliberately disable themselves and nearby misbehaving devices, using a technique called "suicide revocation." Once a node detects that another network node has gone rogue, the detecting device declares itself and its naughty neighbor dead, and shuts down both devices. Under the system, the reporting node shuts itself down to prevent a rogue node from falsely accusing good nodes of misdeeds.

A similar approach that's not so drastic calls for multiple nearby network devices to "blackball" a misbehaver, shunning it and preventing it from harming the network.
