No such thing as "Free". These site make money off of you via advertising and your time. In my personal opinion it seems like most of these sites are set up in order to make the operators money.. While giving the users fractions of pennies in order to have them slave for the site developer.

If you want to get bitcoins.. Get a job and purchase them... OR waste hours of your days on faucets and sites like bitvisotor and get paid fractions of cents for your time..
