I'm scrolling through some Nigerian TikTok hashtags,

and there are posts here with hundreds of comments, thousands of likes.

There's a video here of a young man,

must be in his late teens or early 20s,

and he's wearing a very expensive looking gold watch

and doing a little dance.

There's another video here.

It's got two young men and they're crouching down with a laptop

and they're just surrounded by wads of cash.

And for some reason, there's uplifting gospel music playing in the background.

These aren't your average posts by rich kids on social media.

There's actually a much darker side to these flashy displays of wealth.

The hashtags I'm looking at are associated with a phenomenon called Hustle Kingdoms.

They're communities of con artists in West Africa, where people are taught to carry out a range

of cybercrimes from romance scams to blackmail.

Crimes that are having a devastating impact on people thousands of

miles away. Losing Jordan has changed everything about my life, from my livelihood to how I

watch out for my other children. I'm Dan Hardoon, and for BBC trending, I've been exploring the hidden world of

Hustle Kingdoms, which operate both in person and online. I have managed to find my way into a

Hustle Kingdom WhatsApp group. It's got over a thousand members and how social media is being used to recruit a new wave of cybercriminals.

This guy is saying he can teach you too, but also saying that you have to be loyal to him.

Hustle Kingdoms didn't start out as a social media trend.
