Is hustle from home a spam?

I'm having a great experience with hustle from home. you have to earn $75 before they'll payout (which take a few days) but im having fun with it. from what i understand, companies pay hustle from home to display their ads. (same way advertisers pay TV networks for commercial airtime) the difference is that hustle from home shares its advertising profits with its members. By the time i cash out my $75, im sure they'll have earned $150 for themselves, but that's ok with me!
