PMSL!
I wouldn't be daft enough to wash my windows in my undies, but if I did I would call him a peeping tom at all. If I was walking around my house, nowhere near my windows and the guy was using binoculars to see right in then you'd have made a valid point.
My point is that he chose to do it knowing full well anyone can see him (he was very buff so I suspect it was orchestrated, I'm not complaining though) and I took advantage of it.
In your first post you are implying that anyone who watches BB are voyeuristic, yes we are but not in the shameful way you have implied us to be. The contestants on BB are no different than my neighbour, they're putting themselves out there to be watched, and I'm merely obliging.
