A 1986 U.S. Senate report found that motives for people's collecting child pornography include arousal and gratification; validation and justification of pedophile behaviour; to show the images to children to lower their inhibitions to engage in sex; preservation of an image of a child at the age of sexual preference; blackmail of depicted individuals; a medium of exchange and communication with other child pornography consumers; and profit.[64] A 2012 U.S. Sentencing Commission report found that child pornography offenders, while "much more likely to be sexually aroused by children than contact sex offenders or the general population", can also have non-sexual motives for collecting child pornography, including initial curiosity, compulsive collecting behaviors, avoidance of stress and dissatisfaction with life, and an ability to create a new and more socially successful identity (within an online community). Some offenders find collecting child pornography enjoyable regardless of whether the images are sexually exciting to them; their interest is in assembling complete sets and organizing the material as a pastime, analogously to what a stamp collector might do.[65]
