Is it permissible to accept a commission for a forbidden product (a necklace in the shape of a cross) in network marketing, if a person from the network purchased it, even if I did not market it to him directly?

Network marketing is forbidden, whether the goods are permissible or forbidden. The fact that the goods are forbidden increases the prohibition. What a person gains through this method must be spent on general Muslim interests and given to the poor and needy.
