If you guys haven't figured it out yet, they obviously don't want usernames/passwords posted here. If you have passes to share you can ask people to PM you, or you can find your own since it's incredibly easy. It's better to PM anyways considering there's probably two to three times as many guests viewing this thread than actual members.
To try and find your own passes:
1) Go to the website you want to view, click their log-in link, and copy the URL (for example, BangBros is http://login.bangbros.st-secure.com/)
2) Go to Google, paste the link in the search bar, and hit search. On the left, you'll get a list of refined search options. Clicking Blogs or Discussions will give you lists of websites with username/password to try.
All you have to do is try them until you get a winner, that's all anyone else is doing.
