PeerBlock is a program for Windows that allows users to block information going to and coming from certain blacklisted websites. It is a successor to a Linux-only program titled PeerGuardian, which serves the same purpose. Although PeerBlock primarily uses blacklists found on iblocklist.com, the user can configure their own blacklisted websites, as well as obtain custom blacklists from the internet.
PeerBlock is primarily programmed by a small team of developers who are led by Mark Bulas, and the program is funded by donations from the public. These donations go towards adding features to the program, as well as potentially one day renting a private server that would allow automatic updating through the internet.
The program PeerBlock is incredibly useful when visiting certain websites that you don't want to share your information with, as its easily customizable blacklists make it simple for anyone to block sketchy websites or certain users from accessing their information. Anyone that finds themselves doing a lot of networking and internet browsing should consider using PeerBlock, as with modern technology, it can be quite simple for someone experienced with information technology to access your information without you even knowing.
The customizability of the program makes it easy to use and more effective than the standard Windows firewall, and as such, it is an incredibly useful program to have for anyone who accesses information over the internet, and especially so if your information is important and private. Not only can you customize the interface, but one can also customize the information that is blocked, and it is simple for most anyone to use, regardless of their own personal experience with computers and technology.
