I have a friend who pays his rent through Goldshire on Moonguard (US) and Argent Dawn (EU).
The majority of the people there, as in Goldshire, are 30-50 year old married people using it to express sexual frustration. Stuck in an unhappy marriage but not wanting to be caught on tinder or some camsite, they use World of Warcraft to take out their frustration.
And as the Free Market has taught us, where there's a demand there's a supply. A lot of teenagers and young adults, both men and women, happily whore themselves out for these adults. In a twisted symbiotic expression of sexual liberation found within a rated T for Teens Video Game.
