May I suggest a different tool for would-be "Protector" subscribers?
It's called "talking to your children". Benefits of "talking to your children" include:
1. building up a trusting relationship with them
2. finding out what they are up to in a direct and straightforward manner
3. lets them know that they are worthy of human interaction with you
4. inexpensive
Optional extra packages include "talking to their teachers", "talking to your neighbours", and of course the "I realise that there are not peadophiles lurking round every corner" reality check system.
