it definitely was her fault to some degree 
letting her teenage daughter go out with a man in his 20s is weird even if he's a "family friend" (they only knew him for a few months) and according to Brandon (I'll also admit his word probably isn't trustworthy) he would drop Bianca off at home while she was still high and nobody would notice or care
Also Kim was fully aware of Bianca's online behavior but pretty much refused to take away her electronics for some fucking reason. You know you're daughter has had men attempt to groom her and yet you allow her to stay online and talk to strangers??
