If you ask me if you communicate regularly with you downline that scenario shouldn't happen. Just make sure to help your team as much as possible so that they can be satisfied with the company their sponsor and that way they won't have a reason to go and do other programs. But, in case that doesn't help then there is not much that you can do. Just do things I wrote above and I think that those are best things that can be done as far as you as their sponsor are concerned.
