When approached for these statistics,
several researchers refused to provide it
or said it was no longer available. Such
practices are unacceptable in any
scientific community. Researchers have
an ethical obligation to publish these
basic statistics or to make them readily
available to other researchers; otherwise,
scientific progress is impaired or even
misled. (“Nature or Nurture? A Meta-

The majority of gangs behind digital
piracy make their money from advertising.
A 2013 study in the US of almost 600
“content theft” websites (featuring illegal
streams or downloads) found that they
earned an estimated $227m in annual
advertising revenue. Police forces across
Europe and the US are looking into where
this money goes.
The 30 largest sites in that study which
were supported only by ads made on
average $4.4m annually, but even small
sites made more than $100,000 a year.
This gives them profit margins of between
80-94% – an incredibly lucrative business.
