Not necessarily, IMO.
If he was interested in children, his interest in mature women would be to get to their children. It seems most of these women had children. Perhaps the under age youth that would have access to a computer were simply too young. And childless themselves. Pedos that want access to very young children would find a woman who has children so he can have access to them.
MOO
Using TLM as an example. It has been reported that she was molested as a child. I have been left with the impression that this was a recurring theme in her life -- it happened with multiple men. Men her mother was dating. Men who likely chose her mother so they can have access to her child.
In my opinion, his interest in women with children does in fact convince me of what his interests were. He was interested in women with children to the point where he became involved with a woman while she was pregnant with another man's child. Not too many men would be interested in that... moo.
