Most servers have either a throttle of 1 msg every 2 seconds after a 10 msg burst, or 2 msg every 1 second after a 5 msg burst, or some other formula very near to those. If you continue to exceed the throttle and allow ~25 messages to stack in your queue, you are typically disconnected from the server.
The only way to exceed this throttle is to request an i:line from a network admin.
The network admin will probably say no, unless you've already well established the popularity of your game with hundreds of players over a handful of years. But who knows right?
