I call bs. It's far more likely that the card or email was flagged for chargeback history, the account was abusing customer support (saying items were missing, etc.), you showed up somewhere else doing fraud (e.g., your email was found in a fraudster message board, you were card cashing, you were using stolen gift cards), or any number of things. There's zero reason to believe it's because this person is sex worker without further evidence. This is all just speculation.
