The only thing the majority of victims of rape are guilty of is silence. They are far too often guilty of not reporting the crime.
Some estimate that between 65% and 98% of rapes are never reported to police (depends on country, world region etc).
If you are a serial rapist, and you rape 50 women, you could actually be so lucky that only few ever report it to police, which in reality makes it possible for a single person to rape 50 or even 150 women, and still walk free.
