This is a great question. For any service like this, there should at least be transparency. As a parent, I'd be interested in understanding:

1. How the block list was initially populated

2. What clear and objective rules govern which sites should and shouldn't be included

3. Who determines those rules, and what is the process for changing the rules

4. How often are those rules proactively reviewed or changed

5. How is the block list verified as following those rules

6. What the process is when a false positive or false negative is found, reported either internally or externally

Maybe I missed it but I didn't see any of this information posted on the site.
