You won't see a lack of compliance from the industry in responding to a judicial order. We have judicial procedures in place, if a judge decides that the content on a website needs to be taken down. You won't have any issue—the company or the website host will take it down. This is the problem: the issue you'll run into is what happens when that website is hosted in Brazil.
Adding regulation is not necessarily, then, the best practice. We already have laws on the books that will deal with this issue, and you already have compliance with judicial orders for the content to be taken down. The fear would be in deputizing the ISP industry to respond to these. If a consumer says that he or she wants that information about him or her taken down, how many times are they going to get these types of requests?
There is a judicial procedure for this.
The issue Robert brought up is that the Privacy Commissioner might be better suited for education, as an ombudsperson better situated to educate and work with the provinces through the school systems to educate young people about the danger that anything you post online may stay there for the rest of your life. These don't come down instantly, and when you see young girls posting nude pictures or whatever it might be, once they're on a website they're cut and pasted onto another and another and another.
There's no better way to control it than educating the youth about the dangers inherent with that. Trying to regulate having all of these websites take down this content is an endless game of whack-a-mole, and you'll never be able to catch up.
