Me personally, I can't say. Depends what kind of mood I was in when I clicked the cut. And admittedly, fewer people would probably have clicked the cut to pick up on it in the first place without that out-of-context tease (I'm on to you, schmevil), so the odds of a multiplicity of clever comments such as you might see on a Robin post are low (also, there's less context to make jokes from; a joke like "don't let Bruce see you like that, Timmy" requires worldbuilding and a mutual immersion by fans in that world that PFSC doesn't have).
But yes, someone would have picked it up, I'm quite sure of that.
