This kind of reads like a catholic who brought their kids to mass their whole childhood and disbelieves that catholic priests are child molestors because they never molested your child. They don't prey on children with present caring parents who don't leave their children unsupervised. They prey on solitary, neglected, vulnerable children, or for catholics those who are willing to trust a priest alone with them. In roblox it's the same but without the implicit trust of an authority figure. The pedos probably avoided you. You didn't somehow dodge the shady shit, you inadvertently created a bubble of safety that prevented your kids from being preyed upon because there's so much easier prey around.
