Bugmenot: Bypass Passwords and Bypass Compulsory Web Registration

BugMeNot is a cool internet service that provides an interface with user names and passwords to let Internet users bypass mandatory free registration on many online web services. Many web services requires free registration to view the public content and some of them use these information on file to send undesired spam messages to registered email accounts. Bugmenot creates an interface for web surfers to install those data to their database and share this data with other internet users that do not want to share their personal information just to browse a web content.
You can find login details for most of the online web services including magazines, newspapers, forums, adult services, dating sites, community services and even some social media sites including Fark, Blogger, Gravatar username and password combinations.
After using the ease of bugmenot, I started to check their website more often before registering a free website/forum just browse the content. If the username and password combination is registered to bugmenot database, I use this to explore the content and if I see any value to be a registered member of this website/forum later on, I create my won account.
For frequent users of different websites, forums and services there are some bookmarklets and widgets for popular web browsers including firefox, internet explorer and opera.
