I'm not saying you're nessessarily wrong but that is some shit logic you used to get there. You have a single premise and a conclusion that absolutely doesn't follow said premise. By this logic there should be a drought of hot girls showing anything worth talking about on all the internet.
Yeah. As stated above, your example completely disproves your hypothesis. Reality is that there're many variables that factor into every girls decision of what she will or won't show and when she'll show it. While believing that they're hot is absolutely a factor, it's not the only one or even necessarily the dominant one. In fact, I'd argue that not believing they're hot could make it less likely that they show as it would undoubtedly result in lower confidence that would then require more positive feedback from viewers to overcome. In PVZ's case I suspect that she's a bit of an exhibitionist and is turned on by showing us. In any event, she certainly showed to much to soon from a long term business perspective.
