Definitely. They could do something about this but they would make less profit.

This is, very unfortunately, what happens in every internet space which is targeted towards children and allows communication among users. It is by far the easiest way for anonymous predatory adults to make contact with typically unattended children. I would like at some point to see a child-oriented space on the internet have the highest priority of children’s safety at some point, but there hasn’t been one yet.
