Suggestion on how to suppress "SubscriberNotFound" exceptions

We are publishing message to a Topic (multicast) that has a subscriber that is conditional - therefore, it will only purposely pickup certain messages. The issue is that for messages that do not meet the condition criteria there is no subscriber and a SubscriberNotFound exception is logged along with putting the message in the Failure table.

We've created a dummy subscriber to handle these other messages with a dummy business process with a single Cancel step, but also needed to bind it with a dummy endpoint so it will run. So a lot of dummy stubs. 

Only other alternative I see is to be put conditions within the Publish business process to not publish to the bus, but seems to me to defeat the purpose of having conditional subscribers (plus it's a lot cleaner for us to have the conditions on the subscriber than in a publisher bus process - especially since in the future we may create subscribers for the other conditions)

Is there a better suggestion to do this?

thanks.
