What is the ruling on joining and working with a Moroccan advertising and marketing company that offers various earning methods, including inviting friends, clicking on ads, contributing to forums, purchasing investment packages with high returns, or earning from advertising packages through a six-generation multi-level marketing system?

Earning profit through effort is permissible if the advertising and promotional activities are permissible, and the specified percentage of 12% is known from a known principal amount (the price of the advertising packages); otherwise, there would be a dispute regarding its permissibility. However, earning profit through investment by purchasing investment packages at a value of 10 dollars per package with a guaranteed profit of 120% is not permissible. The remaining scenarios were not sufficiently clear.
