I’d probably be boring and try to use it to improve the lives of marginalised and impoverished people. Getting hospital waiting times down, improving access to mental health support, give people loans to get on their feet. That sort of thing.
Maybe I could also make a video sharing site to complete with Youtube and force them to make some improvements to remain competitive. But I’m not sure 6 billion will go far enough on that front.
The question is, would these people be predators if people didn’t bait them into it? If they are doing this for “content” or some sense of moral judgement, then they have an incentive to push people into these things more than they originally would.
I can imagine the following scenario being common (to the point at which I wouldn’t be surprised if there is a tutorial for it somewhere):
Target some marginalised group as well, and you can also justify hatred towards them and show everyone that your group is better!
