Hot take, elementary school kids shouldn't be held to the same standards of adults. They shouldn't have access to pornography and they especially shouldn't have access to pornography of people they know in real life.

Hot take, it's not the teacher's responsibility to keep children from accessing sexually explicit material, it's the parent's. If children are accessing the OF account of someone they know in real life, then the parents need to sit down and have a frank, age-appropriate discussion with them about sex work, porn, and appropriate boundaries.
