+The spammer node also provides a method to test burst messaging. It will send the total user-message-limit of messages sequentially without pauses, then rests for the epoch period and repeats.

 - Connect a spamming node(s) to the network where spam messages are rejected and misbehaving peers are disconnected for a time.
