What is the ruling on participating in the "Mawja" telecom company's system, which awards prizes based on accumulating personal points and points from cascaded subscribers (the tree) down to the fourth level?

If the points are calculated as a result of subscribing to the website without a financial cost, then there is no objection to them, provided that you do not intentionally consume extra hours beyond your need to increase points; because this involves a semblance of gambling and extravagance. However, if the points are only calculated in exchange for a sum of money, then this is not permissible; because it is a form of prohibited gambling.
