Common Error Type(s) for Malicious Actors

[quackzar]

Currently each active secure protocol is set out to have its own error type for failed checks.
Most protocols will have errors for the transport layer, but these will also have a 'malicious' error that can be 'thrown'. As such a common trait or type for this kind of error could make sense, especially when it comes to handling malicious behaviour.

A sketch for a trait could be

trait Malicious : Error {
    fn offenders() -> &[Id];
}

as such the runtime could chose to handle with the given offenders in a fit manner, either excluding them and continuing, banning them and aborting or something else entirely.
