please summarize this challenge scenario

YA librarian in urban public library. You are the YA librarian at a neighborhood branch of a large, urban public library in [City, Province] that filters internet terminals in compliance with obscenity and hate speech laws. You do not, however, filter social networking sites such as TikTok, Instagram, and Twitter, destinations that are one of the major draws (other than Gaming Night) for your YA patron base. Mr. Levesque, a local businessman who was active in lobbying provincial MPs in favour of children's internet protection, approaches you with his concerns about social networking in public and school libraries. He is concerned that such networks endanger teenagers and children because they "open the door" for pedophiles to masquerade as teens themselves. He wonders, if pornography is filtered from the library's internet terminals, why not "pornographic speech" that is exchanged between teenagers, and worse, between adults and teenagers? At your request, Mr. Levesque files a complaint to the library board, asking that it change its policy on social networking sites. Meanwhile, a provincial bill is currently pending that would make blocking social networking sites mandatory in school and public libraries that accept public funding.
