Her scamming people is wrong, no doubt.
If your homie, or you yourself, is emptying a bank account for some e-whore though, that's also wrong. You gotta be smarter than that or this kinda thing's just going to keep happening.
Also onlyfans doesn't give a shit about this kind of bait and switch, they never have, likely never will. The correct course of action is to spin up social media alts and comment on all her shit saying that she's a non-nude model pretending to sell nudes. Do that enough and, at very least, you save other bros the trouble, at best, she whips a tiddy out for real, at medium, she starts advertising accurately.
