Безопасен ли freetour.com?

I'm a guide and it's true, you have to pay a fee. But it's less comparing to other platforms and they really bring you a lot of guests. but considering the page it's well done, easy to handle for the guides and costumors. Four stars for that, but one star less than five, because it's still true: you have to pay as a guide, although it's called free tour
