I honestly dont see how this will make anything even better than before. Is the largest issue here that you can pay your partners?
I see no problem with that at all,if someone wants to pay to be in relationship(or being paid to be in the relationship),so let it be.And this project will make it easier fot those are are into this,so it has my full support.
So on the platform you will be able to find someone you can pay for having a relationship with you?
