The Playboy machines are taboo at my house... because I think they suck! Actually, I kind of like the Stern one, but I think I like it on quarter-a-play play, not "around all the time" play.
If the gameplay was good enough for me to haul one in, I don't think the name would stop one from coming in. And let's face it, those machines (and even Miss World) are not "nudie" enough to be porn. If this was Zingy Bingy, I'd feel differently about it.
