It will also be the official movie store for Roku devices, replacing the FandangoNow store. If you have a Fandango account, you can move your movies over to the new service by going to FandangoNow.com
They don't all require you to provide proof. We had some friends that didn't like their mattress, and a few months into their trial, asked for the refund. They company asked them to donate it to someone in need, and they gave it to us. We, in turn gave it to someone else after we upgraded, but they never asked us for proof.
The Paper didn't provide much detail about their methods. What type of filter was used. Are they using a software filter that only filters the computer that it's installed on?, or an ISP-Based or DNS filter that filters all the computers, as well as mobile devices? Maybe software filters don't work well, but I would say that ISP based of DNS filters do work pretty well. Also, it seems the teens are self reporting their porn viewing habits, but that doesn't mean they aren't viewing it on their phone, or at a friends house who doesn't have the filter.
To answer your question, if your ISP doesn't have an optional filter, the best option is OpenDNS, which you can use with your WIFI Access Point to filter every device connected to your network.
