hanab,
Is your issue that the content was objectively inappropriate, even for frum adults? Or that it’s not appropriate for children?
I don’t know what specific details you’re talking about, but I have more sympathy for the first cause than the second. There are many frum publications that are meant for the frum ADULT population to read. Parents should not allow young children to read adult magazines, since they often, and IMO appropriately so, discuss sensitive topics not intended for children.
