In Asia, the Middle East, Africa, and in Latin America, where it's the Mexican, held to match with his message of discipline and self-improvement, who dominates.

To his 11 million followers, Altamuch is part internet star, part self-help coach and part big brother.

He inspires me, this fan says.

He helps me move forward.

He's helped so many men with depression, another says.

But to others, Altamach is preaching dangerous ideas to young men about their place in the world and how they should treat or mistreat women.

Thank you, thank you.

We've come to downtown Mexico City to meet a woman called Ana.

Ana's former boyfriend was a big fan of the manosphere.

Not just El Tamach, other influences too.

She's in her mid-30s.

Ana's not her real name.

I ask, what was her ex-boyfriend like?

She switches to Spanish.

I ended up with a man who believes the same thing.

Anna began wearing more makeup because her boyfriend wanted her to be more feminine.

She had a good job, but she started working less because he said women were supposed to stay at home.

I was totally emotionally dependent on him, economically too, but it was never enough for him.

If she didn't do what he said, he'd get upset.

Eventually, he turned violent.
