I was looking into using a content locker on a couple of my sites/pages. Thing is, I have very rarely stumbled on any sites that lock content. I would like to browse for a few. Does anybody know what keywords would be good to use to find content locker sites? I just want to see some examples. Also, where can I find free/or purchase media for content locking? It seems strange to me that I am having trouble even finding content locked sites, it would seem to me that it would be hard to avoid them. This method still works... right?
