"Seduction" type pedophiles have the ability to molest astronomical numbers of victims over a period of years, usually when its finally uncovered, the victim count is staggering
This type of pedophile (someone with a defined sexual preference for children) views children as willing and able sexual partners.
In their mind they engage with their victims the same way 2 consenting adults would, however they must first overcome any objection and uncomfortable feelings the victim may have m this is done through "grooming"
Though they are fully aware its wrong and illegal, and that there are treatment centers all over the united states , they choose to act on their deviant urges anyway.
Grooming is an ever continuing dulling of the victims resistance to to increasing odd sexual behaviors the offender demonstrates. They often give the victim an abundant amount of attention, ply them with gifts, they will spend a lot of money and spend an inordinate time with the victim. What they want is 3 fold, 1) for it to NOT to appear out of the ordinary to be with their victims, 2) to lower the victims inhibitions to the ever increasing physical aspect and 3) to in debt the victim to the offender.
They will often decorate their homes in a youthful manner , or have youth oriented objects and areas in or near their home
They may pretend to like child like activities, such as gaming etc, they'll often feign interest in the victims personal matters, such as dating, school, sports teams etc..
They may deter the victim from revealing the abuse through a variety of means from a feeling of loyalty, to smear campaigns, to threats of violence etc...
They will often befriend the victims families as well using the same debt producing tactic to make parents feel like it would be wrong to NOT let their child spend time with the offender.
I say "victims" because of the nature of their deviant desire being based more on appearance than actual age, once a victim outgrows what they are attracted to , they usually move on to another. Its also not unheard of for a single offender to be victimizing multiple victims at the same time.
The seduction type offender desires a sexual relationship with the victim, similar to what consenting adults would, what they want a "lover" but their desired partner is pre-pubescent.
Due to embarrassment, along with any threats the offender may have issued along with the fear of not being believed, (primarily in the case of celebrity offenders) the victims of these type of crimes, often keep it to themselves, usually with an extremely damaged psyche, left to deal with the pain and damage all alone.
Meanwhile the offender simply carries on until he is apprehended, by then the number of victims can number in the hundreds (usually anywhere from 50-300) .
In this case, sadly Sandusky's reputation allowed him to carry on for decades harming scores of victims, some we may never know but hopefully eventually they'll come forward
