ScrappleFace is a satire website...
so no, it isn't real.*
As for "Reality TV", it does show how some carefully selected people behave when put into contrived situations. I've only watched a couple episodes of "The Greatest Race" (which was fairly interesting) and maybe 1-2 episodes of "Survivor". The shows just never could hold my attention.
*ScrappleFace was the site that coined the term "Axis of Weasels" back in February, a rhetorical shot that was heard around the world and an instant Internet hit.
