I think pavel_lishin's comment is alluding to that what we are reading in mvdtnz's comment is victim blaming. It is a bit coded. Being overly concerned what a female victim of sexual assault was wearing is textbook case of victim blaming. I believe this is what the sentence "I bet they were wearing a real short skirt, too." is evoking to say that the sentence quoted from mvdtnz's comment is blaming the victim of the scam.
