From their own info page they clearly state it's parody
This website was created in 2009 as parody of whitehouse.gov called "not The White House". In 2012, a parody of the NSA website (Domestic Surveillance Directorate) was added. In 2013, 'IC OFF THE RECORD" was created to track the Snowden revelations.
In 2016, "White House Info" was launched providing detailed information about various White House related topics such as White House Tours, Easter Egg Roll, Camp David, and others.
