The idea crossed my mind. I know in PushCrew and some others you have the ability to import/export lists. Now, it's blackhat for sure, but I'm wondering the possibilities of let's say seller builds a push notifications list of 5,000 people in health niche ex, then sells that list of subscribers.
I'm not saying I'm planning to do this.. just the thought was interesting.
