I guess I'll start.
We haven't thought about what the penalties would be. I'll be quite honest; that hasn't been our area of thought process.
We have seen this in two ways in the U.S. To ensure compliance, there have been sweeps from time to time of the sites that would be the most obvious—I am speaking especially of children and youth in these cases, sites targeted at children and youth. The other way is simply the reporting mechanism that might happen from citizens and others who are concerned about behaviours that are egregious or out of line that could be reported, so it would be a sort of self-reporting mechanism.
Aside from that, you do need something like a sweep mechanism that allows you to do what they've done in the U.S., a survey of sites and a report on compliance, with the possibility for fines and some kind of corrective measure.
