Not worried about click fraud, but..

More concerned about demographic "fraud" or view "fraud". Generally speaking, companies marketing higher CPC/CPM value items will be paying more to get their ads seen.

Average Joe puts his greedy BAT user hat on, and searches/peruses the most expensive markets he can find - even though it is stuff he does not need, want, or can't afford.

Say he uses this list and just goes straight bananas : http://www.wordstream.com/blog/ws/2017/06/27/most-expensive-keywords

Does BAT have any answer to this? How does BAT gauge/match intent and the user's true demographic.
