Consider coming along, in the middle of a 45-year practice and suddenly
declaring the an independent entity, with whom you have no business
relationship and who has been doing legal things for those 45 years,
should now stop their legal practices because you've decide to impose a
new policy on them.
Forget technology. Consider the inter-organization implications here.
MLMs are independent. They take delivery of a message. Delivery, not
simple relaying. The post a new message.
You've suddenly made their existing practice fail and so, as is common
and famous for the Internet, they start routing around the breakage
you've created.
Please explain how this "should not" you want is reasonable. Then
please explain how it is likely to be effective.
