I think that just blocking access for a teenager is not very helpful in teaching them about the internet and it's dangers.Far better to educate and trust your teen whilst setting firm boundaries and sticking to set punishments when those boundaries are crossed.

After all out on the streets you either let them out to learn how to traverse the world with your checks and balances(ie what to do in a certain situation)or you lock them up and doing this will prepare them for nothing.Everyone eventually learns by experience .Try to trust your children and IF you communicate well with them you should ensure that they will mostly follow the rules.
