Same here. As you say, maybe it's partly to not give other potential abusers ideas. But like you, I wish they would have. Whenever I see shows like this I really want to know every detail just because I have such a deep curiosity about crime and social dynamics etc. I guess there's also an argument that knowing all of the details about how exactly he pulled it off could also help potential victims in the future?
But for what it's worth, as I mentioned before, i'm certain that the reason he was able to pull it off is because all the girls assumed he was gay. First thing I noticed on the program (especially when he answered the door to the police) was how camp he looked and soudned.
He'd be able to get away with so much and a completely different approach if girls thought he was gay. I don't imagine there was anything especially clever about 'how he did it' as you say. I imagine him approaching girls on the dancfloor and being really high energy and over the top. Some compliments and making some of them laugh. Then bringing a tray of shots over for them to drink and pointing at his VIP table etc. But the point is, all of that would only 'work' due to them assuming he was gay. I mean, I have lots of straight friends who are always trying to pull girls from bars and that wouldn't work for them! Girls guards would be up. They'd assume my friend was trying to pull them and, assuming they weren't attracted to him/he wasn't her type, they'd just tell him to go away. But with Craig, they'd think 'oooh, he's fun and he's obviously not trying to get in our pants! He's one of the girls!!!' and before you know it, he's got 8 new phone numbers in his phone and he can slowly escalate to house gatherings etc
