Over the years, there's been plenty of fuss about children spending their parents' cash on in-app purchases.

It's been great copy for newspaper headlines and governments from the US to the UK have considered legalisation, while Japan has put hard limits in place.

On that basis, the finding that 41 percent of children who are 'allowed to make IAP' (whatever that means) know their parents' account details could be the root of the problem.

Of course, as with all surveys, size matters. In this case, this was a mere 87 kids.

That was because of the initial survey size of 500, only 17 percent are 'allowed to make IAPs'.

In that case, the elephant in the room is the number of kids who aren't 'allowed to make IAPs' and know their parents' account details. You can see how that's going to end.
