Not to talk about how they rent you refferals that make little or no profits for you so they pocket that extra money. They disguise it as advertising packs also for legal reasons. You got something in return( the adpack)
That means it is not an investment just a purchase. I'm not sure exactly the details but I know its to get around some legal bs. I don't have an issue with people using loopholes but they exploit it for self gain and greed.
Plus it isn't even free you have to login every day and if you forget you get no referrals payment that day. Some people say clicking ads is not work but it feels very much like work after a few months.
