The technique used by grooming gangs in the UK is as follows: get the child to do something the parents wouldn't approve of (smoke a cigarette, drink, do drugs, etc) and document it, use that documentation to blackmail the child into doing more. It becomes a spiral that the kid doesn't know how to escape from.

The way I hope to prevent that is to ensure that my daughter knows that, while I may disapprove of things like drinking, I'll always forgive her. I also make her clear on the line adults should not cross.

Besides that, I try to build her self esteem and street smarts as much as I can. In addition I have her question authority, myself included.
