Can you explain your thinking? as I find this so far from likely to be true that I can't understand how anyone could believe that.

Example of one calculation method, take the probable incidents, multiply the probability by the negative impact. Likelehood of kid injurying themselves in a physically dangerous area, very very high. Hospitals are full of kids every weekend that injured themselves in their own home, negative injury likely bad bruise or broken arm lasting days to weeks. Online probability of harm = low. Severity of harm most likely = name calling or mental bullying. Bullying impact likely low unless bullies also physically live nearby which then brings it back to in-person harm.
