What is “rack”?
Risk Aware Consensual Kink or RACK is a recently defined code of conduct in the BDSM community created to replace SSC. It means that a BDSM activity is ethically acceptable as long as everyone involved is of the age of consent, is aware of the risks involved and freely chooses to participate in that activity. The premise behind it is that some BDSM activities may involve risk of injury and may be considered not sane by others (individual perception of what is safe and sane can vary), but as long as the individuals are fully informed of the risks involved and consents from an informed consent position it is okay.
