>"porn viewers don't have a huge incentive to make sure PORNHUB CO. doesn't appear on their bank statement"

Do they? I mean, honestly, who isn't a porn viewer? Who on earth would you, personally, think it to be scandalous to have a porn subscription discovered on their credit card? Anybody? What is the incentive?

I thought OP's porn example was pretty good. The entire world crushes porn (even when it's taboo or illegal), and yet still refuses to pay for it.

I'm pretty sure people who have a not terribly high opinion of me would have it lowered still to discover I paid for porn.

Eh, they are probably too busy looking at porn to care.

> Who isn't a porn viewer?

Believe it or not, there are people who never watch porn. The industry's sleaziness turns some people off, and some people just aren't into it.

I think it's very insular to assume that what you think is normal is the same as what most people think is normal, especially when it's still newspaper scandal material.

http://www.independent.co.uk/news/uk/politics/smith-ordered-... : mostly this was about putting the cable TV bill on expenses, but all the papers were particularly outraged at finding PPV porn on the bill.

Also, the porn industry's billing practices are sleazy and full of dark patterns.

another effect of private browsing is that, by default on Chrome, extensions are disabled. Therefore it is possible they suffer less from ad blocking than the rest of the industry.
