These IG hoes that AREN'T on OF usually make their money from a combination of:
1: Unreported clothing, supplement, alcohol, resort/travel sponsorships. A girl from my HS had a niche IG with 5-10k followers and made a few K a month from this as a side hustle.
2: Family wealth. Plenty of these influencers aren't making much money at first or at all and they have outside income or support.
3: Appearance fees. This verges on prostitution. They can be booked for parties and events with no requirement for sex. Just being there and being hot. Dan Bilzerian used to pay girls for this to seem cool. Sometimes this bleeds into psuedo modeing gigs.
4: Sugar Baby/Escorting. A few trips a year at 10-25k plus gifts can make for a pretty lavish looking IG feed. A DIFFERENT girl from my HS was a THOT in her 20s. I'm pretty sure she was a pharma rep or something - but she definitely was also a sugar baby for rich yacht guys. Her IG has like 20k followers and Roberto Cavalli and other rich old men had her on their yachts a few times a year with a bunch of other IG hoes.
I know we are all waiting on something good from her, but unlelssy you can afford her, I wouldn't hold my breath.
