I reckon you need to be real careful. My 'suspicion' is that there are a number of firms out there, perhaps traditional direct selling organisations, who have decided to adopt almost a 'PicnMix' attitude to sales eg they have a 'traditional' stream where you can just earn a commission on goods you sell to supplement income and a more aggressive stream which you can access 'on request'. (And said 'request' might be very much down to which mentor you had - you could, for example, have a 'I don't know how you do it, Ermintrude? Oh Darling, you're clearly meant for better things - why don't you join the XXXXXX stream and that way, you'll help other people and get commission on their earnings...........?'
Do your due diligence with great seriousness - as set out in botwatch if I recall. Ask for - nay, require - properly audited figures before you sign on the bottom line and possibly give up a job/hand over large amounts of cash.
