My thinking is that if you can lose at something on purpose then skill is invloved. It is really easy to be a consistent loser in No Limit Hold'em on purpose. Just make a habit of putting in 80% or 90% of your stack in pre-flop and then folding after the flop. Another way of losing consistently is to make calls where you can't even beat 95% of the bluffs.
I'm not sure if it is this easy to lose on purpose in DFS.
