For the record, "FSM's" weren't staff members, although staff members could and would "FSM" (when they did, their commissions went to staff pay, or were supposed to). And, there were two types of FSM's.
There were those who thought Scn was a good thing, and introduced others to it. They used to get 10% commission on auditing, and 15% commission on training that their 'selectees' bought. From my experience, those who introduced people to Scn, could only do it when they believed in it.
Then there was another type. The types who worked with the registrars, at selling people the 'high end' of the bridge. Some of these types (many who were OT umpty dump), were just in it for the money - they used their 'opinion leader' 'status', to get people already on lines to convince people to pay big money for the upper levels, L's and things.
Many of them were just 'reg'es' (not fsm's). They weren't on staff or SO crew - they were people who the reg'es would use to 'tag' on a reg cycle. Often with these cats, there was little regard for what was 'good' for the person - it was more about what was good for the org (money in the bank).
An "FSM" per definition, would have been someone who would have put the person's interests at heart. Often, the reg'es would by-pass fsm's who did this, 'cause they didn't get what they wanted. They'd get one of these 'other' big shot FSM's in, to help do the trick.
Per FSM policy, if one's selectee was on lines, then FSM commissions could only be paid to the FSM who got them on lines. However, when it came to these "big guns" (public reg'es, 'not' FSM's), these cats got the commissions, and the org would turn a blind eye to it, 'cause they wanted these guys on side so they could keep getting the bucks. It was a real scam that stuck out like dogs balls - one separate to the overall 'scam' of the CofS.
