What the plot of this story? Blackmail, coerce, drugs? How'd they get her to humiliate herself?

Base +6

Erika, a tough girl who likes to stick up for weaker people, tells some girls that they smell bad from the cigarette smoke and says their lower body probably smells as bad as their breath, so they jump her the next day by pepper spraying her and taking off her clothes and videotaping her doing naked dogeza and continue to blackmail her into doing stuff as well as threatening her with being sprayed again.
