I thought it was a side effect of "know your customer". Sex work is high risk because it's adjacent to trafficking (organized crime) and underage workers result in CP. It's very difficult to determine if every amateur sex worker is a consenting adult.
What about sex toy shops? As small provider selling selected sex toys you constantly face a PayPal and stripe (or whatever) ban. IMO it makes no sense.
Or a portal for prostitutes to advertise their services. I tried forever to find a way to charge CC or PayPal but it's impossible without a huge existing volume. These providers basically enforce a monopoly on this market. Even thought it is completely legal here.
For me the US is enforcing their moral believes on us. In my culture this differentiation does not make sense
Given how cryptocurrencies are rapidly growing (again), we should expect their deeper integration into payment systems. Eventually, all sites related to sex toys, sex services, or any kind of sex pleasures will shift to independent payment systems based on cryptocurrency. As for me, I'm not pleased too with this monopoly while hiring babes on https://aurumgirls.co.uk. You said that "the US is enforcing their moral believes on us". I think it's their state policy. You need to follow their rules and believes, otherwise you are "wrong".
I wonder if that is related to dodgy subscription schemes on porn websites as well. I looked into it a few times and every portal had ridiculous hidden subscriptions. Every access pass automatically converted into a hugely expensive monthly subscription. And I presume it is similarly hidden or difficult to get out of it again.
I'm really happy to pay for content, but shit like that makes me nope right out of there and look for alternatives or not bother.
Businesses with high chargeback rates might get rejected by some payment processors, but there's usually another one willing to take them on in exchange for higher fees.
Post nut clarity is apparently a financial problem.
