Overview
The scammer goes to great lengths to convince the victim the scheme is not a scam, or leverages the victim's prior scam knowledge in some way. Common in scam types that are common and well-publicized, or where there is some wariness developing in the victim pool, such as in Online Marketplace Scam Buyers.
Other cases where this technique works include:
2.2.5 OTP Or Phone Verification Scam: the target's anti-scam vigilance becomes the mechanism by which the scammer asks for an OTP code ("I'm going to send you a code to prove you are real").
2.2.4 Fraud Loss Recovery Scam: the target's recent victimization has made them hyper-aware of scams, and that awareness becomes the lever for a second scam disguised as anti-scam help.
6.3 Protect Your Money Scam: the target's general scam-awareness ("scams exist, accounts get drained") is what makes the protective pretext plausible. The fact that they know scams happen is the reason the pretext lands.
2.1.7 Pet Purchase Scam: scam-awareness becomes shared identity. "We're both wary of bad-faith people in this space" allows the scammer to extract large sums of money from the victim under the guise of proving they are worthy of this expensive pet. It's more "we're on the same side against scammers and animal abusers."
