Normally it cannot happen since we're communicating at least once per week trough mails. But what can eventually occur, especially when the CSA is no longer interested in business, he/she will remain indifferent to any contact you try to maintain to him. In my downline for eg. there are people I personally brought into SFY which are no longer interested, intesd of OPT OUT, they are STACK. They do nothing, months after months. I understand that each and any choice must be done wisely
