So grotesque violence appeals to fewer people, but banning gets focused on material more people find acceptable, even desirable?

This really is a culture/posture driven issue.

It is not as if many people think (emphasis on "think", as in being honest, reasoning carefully and being scientific about evidence) that banning sexy curves in a video game is going to impact the prevalence of sexy curve imagery, or "save" anyone from anything.

Imagine if financial companies required their employees to sign a legal statement committing to not "use porn, escorts, blow ... or spicy video games!" So strange that they don't do that!!

Financial companies like to make a show of having "high standards" when it comes to "controversial" segments of the market, or unfortunate individuals who don't fit the mold, when that gets them a lot of showy theatre for being hard asses to their audience of regulators.

While keeping very quiet, and not looking into things too hard, when it comes to tens of billions of sketchy dollars going through their systems associated with very high net worth criminal actors, organizations and corrupt governments.

Epstein did not lack for financial services.
