Yes, now there are many projects like this, and most of them have the same method of work, only the games aredifferent , but they have the same principles the sam method of promotion. The question is whether society really benefits from them? The majority of these projects are scams and are criticized by their participants.
And as we see, the big beneficiary is the work team or the owners of the project and some other people for several different factors
Those kind of trends cannot last, and this is because at some point a saturation point will be reached and no one will be able to earn any money from those projects, then add the scammers on top of it and suddenly a trend that seemed impossible to stop will die down as quickly as it began, then I would not recommend anyone to participate into it or they will put themselves at risk of wasting their time, like many people have done so before them.
