Ignite parental control time limits easily bypassed on iPads

[lovetheinternet]

My son has a iPad purchased last year, fully updated.

There is a "Private Address" WiFi option that masks the iPad's MAC address.

Toggling this allows him to easily get around the parental control time limits set up in the Rogers Ignite app.

Any solution apart from telling him not to touch that option?

fyi - I solved this by blocking both the iPad's normal device that uses its normal MAC address, AND, by also blocking the iPad's other device that uses its private MAC address.  Luckily, it seems that I only have to contend with 2 MAC addresses as the iPad doesn't generate a new random MAC address each time you turn on its private address feature.
