Everyone's repeating the 73% number, like it's some shocking statistic.

It's meaningless number in isolation. For example if backpage.com captured 70% of the sex ads market, I'd expect it to also capture the sex ads related crime at the similar rate.

If craigslist has 90% of ads for selling beanie babies, it will also have a hand in significant majority of beanie babies selling related crime.

So the question should be how big backapage was when it came to sex work ads, to make sense of this number.
