A woman reached out to me on Instagram, then switched to WhatsApp. She introduced her part-time job, involving being part of an online purchase syndicate that artificially boosts sales orders to enhance the reputation of online stores. Numerous teams specialize in this practice, known as "刷单," to obtain rebates through fraudulent orders. I suspect this syndicate is linked to online purchase scams and other e-crimes. I wanted to bring this to your attention.
