A bigger issue is why this minor didn't bring the issue to their parents, and instead chose a random online friend to report this predatory pedophilic activity. If this child can't even report things like this to their parents, there's a much bigger issue than some unknown FFXIV player saying nasty things to them. That is, in the end, only text.

If this child were to be attacked physically in real life, they don't seem to have the skills necessary to properly handle the situation. Would they run home, log on and again try to get help via FFXIV? That's a parenting failure in the extreme.
