The cynic in me might say its function appears to be to match homosexual predators with groomable, confused boys.
This is true of Boy Scouts, YMCA, Girl Scouts, schools, Day Camps, Sunday Schools, City Athletic programs and anywhere kids congregate.
If an adult wants to spend time with your kid be suspicious or at least on your guard.
I am generally quite suspicious of any male adult who wants to spend time with children which are not their own; it appears to be a universal trait of predators.
