I made a video of a flood on Facebook once and someone from viralhog contactede about licencing them the video. It took me a couple of hours to fill out the paperwork around work. By that time there were new videos coming to light and I never got any money. A way to stack zaps where the original user gets a cut of the zaps and the media outlet or influencer gets a cut would be ideal. You could agree on the cut in order to get your post reshared.
