My opinion for what it's worth
I believe that anyone who can bear to do so should study these pick up artists and their techniques.
The technique described in the BBC piece is called "escalation" and a youtube search for "pua" and "escalation" will bring up some videos worth reflecting upon
Also it is worth understanding that there are many similar shcools for women, only instead of PUA they are called Goddess schools / academies or schools for seduction and similar names
There is a fairly awful 2004 film called School for Seduction that features exactly this kind of school
trailer here
the entire film can be seen on youtube but in a very poor quality upload
These is an intersting clip from the film here, with Russian language overdub. These kinds of school are all over Russia and Eastern Europe.
By some strange coincidence the writer for School for Seduction, Martin Herron, is also the screenplay writer for the film Irina Palm, a strange film in which an elderly lady regains her self-confidence by working in a sex club masturbating men through a hoole in the wall. She ends up falling in love with the pimp / sex club owner, and he with her due to her amazing masturbation techniques.

Of course the difference between the PUA schools and the schools for seduction is that the latter claim to teach women to either marry a millionaire or to secure gifts and money from men.
The schools operated by cults claim to empower women by training them to be goddesses, however the "goddesses" usually end up working as strippers, pole dancers, porn actors, sex cam girls, escorts etc.
Their role can be to earn money for the guru / cult but also to seduce politicians and people in positions of influence and serve as bait for compromat.
Jeffrey Epstein's network operated in a very similar way on a number of levels
Extremely vulnerable young women were groomed via a pseudo-academic process and were taught skills of how to please men sexually.
Young women who were the daughters of extremely inflential people such as politicians were also groomed and abused.
The main difference between the MO and the 2 different groups of females is that while the former were used as bait for obtaining compromat on people of influence (via compromising film and photos), the latter were used to blackmail and compromise their parents. Nobody wants to see their daughter sexually degraded on videos on the internet and powerful, influential people especially don't like it.
