How do you stop it?  

A provider knows what destination IP traffic they route TO a customer, don't they?  That should be the only source IPs 
they accept FROM a customer.


If you don't route it TO the customer, you shouldn't accept it FROM the customer unless you have made special 
arrangements with them and verified they are entitled to source the traffic from the desired IPs.
