But this is not the area I am expert in.
If I might add something. Hacking sites is increasingly difficult and time-consuming. Instead of spending days or weeks trying to get into a secure site, you could spend one hour delivering pizzas and pay for a month or two subscription!
I`m not saying that to preach, I was going to tell you what I do. I subscribe to a site, then immediately cancel so I only get billed for one month. Then I use a program like Offline Explorer to download the content right away, and once more right before my subscription expires. Then when I want to grab more, I wait a couple of months and subscribe again for just one month. Most sites are less than 20 bucks so it`s a very productive way to enjoy a site and winds up saving you in the longrun I`m convinced of it.
