This bill creates the "Autism Spectrum Online Protection Act," which makes it an offense for a person to use an online platform to engage in the grooming of another who the person knows or reasonably should know is an autistic young adult subject to a conservatorship. A violation is a Class A misdemeanor, punishable by up to 11 months, 29 days imprisonment or a fine of up to $2,500, or both. This bill urges online platforms to implement and enforce policies to prevent and report these grooming activities that target the highly vulnerable population of autistic young adults, including building a relationship, trust, and emotional connection with the intent to commit an act of exploitation, sexual abuse, sextortion, or trafficking. This bill provides that family members or conservators of autistic young adults subject to a conservatorship should have access to tools and resources to monitor and protect the online activities of autistic young adults.
