Society holds such jobs in low esteem, so the kind of people who take them are the ones that are not worried about their reputation. There are a few who buck the trend and keep it classy, but most are just the kind of people who will do anything for a quick buck, including double-charging paying customers.

It's a viscous cycle, really. We treat porn producers like dirt only only dirty people want to take the job which further reinforces our stereotypes about said people. Plus the barrier to entry is real low and brand loyalty is almost nonexistent so it's a prime industry for fly-by-night operators.

I knew someone who was involved in the 1-900 business in the 90's. Apparently back then it was relatively common to DoS your competition by running up a lot of fraudulent calls to their numbers. The hope being that the telco would cut them off, and you'd have one less competitor.

For my friend who was hit by this, it really sucked, because telco billing chargebacks in those days took 3 months or more, so it looked like he had hockey-stick month-over-month growth... until suddenly he didn't, because most of the "growth" was fraudulent charges intended to get him shut down.

Sound like a sort of catch 22. Payment processors treat them as second class citizens, so first class who would not do shady business don't dare set up in the industry. And so the reputation of the ones who do validates the processors' line of thinking.

At a guess, people are less likely to make a fuss about fraud when they're embarrassed to admit they were trying to buy such things.
