BMF.io doesn't do any fancy multi-level commission stuff. It looks like a straight-up affiliate setup where you share your promo code, and if someone buys through it, you get 10–50% commission. Simple as that. No extra tiers or getting paid from people your referrals bring in. Just you, your link, and your earnings. If they ever add more levels, that's great, but right now, it's pretty basic.
