A lot of these scammers are actually just indentured servants in the modern era. There’s a ton of different media reports on just how awful the industry is for these “workers”.
These people are literally trafficked, enslaved, and tortured by the modern era mafia basically. Their families are threatened, they’re threatened. It’s not great.
So when they think someone’s on the hook but it’s just someone fucking with them, I would imagine they get a bit angry.
