After looking at the vouch copy I can say this method is legit as mentioned.

My opinion is this would be best suited to someone in a low paying country as its alot of work for the payout but its very possible to make $10/Day even more if you don't mind typing and clicking alot.

Personally I would not do this as I don't have the patience or the time to do this as I can earn more working my 9-5.
