On point 1, that is the incentive to perform right there. These guys are having all of this sex and being naked etc....for the fun of it first I hope, but at least second is MONEY.
On pijnt 2, I think the question is this, did the tenant hide on purpose to avoid the cams. There is a huge difference between having sex under blankets because it creates an intimate space for love making and purposely hiding blankets to avoid the view of the cams. The things Ashley was doing was clearly hiding on purpose to avoid the cams. I think this is where you guys need to be on top of it. You should know better then us if a tenant is truly hiding.
