Is using bank affiliate links for promotion and attracting subscribers to earn commissions from their money movements in surfing companies permissible or prohibited, especially given that there is no direct investment?

If the prohibition of dealing with usurious surfing companies is established, then it is not permissible to promote them using your special banking links to acquire subscribers and commissions. This is because it constitutes cooperation in sin and transgression, which Allah Almighty has forbidden in His saying: "And cooperate in righteousness and piety, but do not cooperate in sin and aggression."
