Pastebin.com, LodgeIT, Pastie.org and other sites can be used to gather information from hackers. The sites can also hold information on employees that might be used in social engineering attacks. Lulzsec has famously used the site to post information that embarrasses those they target and was also the venue of choice for those responsible for the hack of certificate authority Comodo. Pastebin is one of the largest file sharing sites and was created as a resource for developers to share code and collaborate on projects.
