I'm forced to see it both ways. I find creepers (and many posters in this thread) to be very distasteful, even cringeworthy.
On the other hand, it's hard to feel sympathy for people who engage in attention seeking hobbies, and then turn around and complain that they got more attention than they bargained for, or not the kind of attention they wanted. I'm not trying to blame the victim here, but I really think it goes both ways.
And back on topic, I'll just repeat what I said before in different words. For me personally, nothing of value was lost here. I have no opinion on the individual, positive or negative.
As an additional side note:
Having dated a cosplayer, never date a cosplayer. I'm not bitter, I'm experienced.
