A victim who is not considered an ideal, or real victim, is one who leads a "high risk" lifestyle, partaking in drugs or alcohol, or is perceived as promiscuous. A victim who intimately knows their attacker is also not considered an ideal victim. An example of a sexual assault victim who is not ideal is a prostitute because they lead a high risk lifestyle. The perception is that these behaviors discount the credibility of a sexual assault victim's claim or that the behaviors and associations create the mistaken assumption of consent. Some of or all of the blame of the assault is then placed on these victims, and so they are not worthy of having their case presented in court. These perceptions persist in court rulings despite a shift in laws favoring affirmative consent- meaning that the participants in a sexual activity give a verbal affirmation rather than one participant who neither answers negatively nor positively. In other words, affirmative consent is yes means yes, no means no and no verbal answer also means no.
