Is it permissible to subscribe and invest in a for-profit website that relies on purchasing advertising packages for $1 in exchange for 70 website visits and 3200 points, achieving a 159% profit margin, with the possibility of earning from viewing other members' ads and inviting friends, knowing that the website's profits come from car imports? And is it permissible to work on it without investment, or to attract new members and profit from them without knowing their intention to invest, or to reinvest profits without personal financial investment, or to sell the account if the work involves usury?

It is permissible to profit from advertising websites if the following conditions are met: free subscription, permissible advertisements, no deceptive practices to increase clicks, and a known financial return. Therefore, it is not permissible to subscribe to this website because it is not free, and because the reality of contracting with it involves paying money in exchange for advertising your website and profiting from clicking on ads and inviting others. This is forbidden because it involves gambling and usury. It is not permissible to sell accounts on this website or to invite others to it because the contract is forbidden. As for selling your website itself, there is no harm in that.
