A marketing campaign at launch makes sense to me - it's what many offline businesses would do and there is sense to it. There is also some sense to waiting for a bit to make sure the corre website is really debugged and converting as intended. In the offline world, a restaurant might do something like this for their first month or so.
Whether your initial marketing gets the site filtered by Google depends on what you mean by "aggressive". If your actions do not generate a real and genuine response from the public, then the footprint of whatever you are doing might well cause some trouble.
