"To whom it may concern,

I have discovered an international child porn sharing ring which I believe to be much bigger than any previously known or imagined.

The ring operates openly on the Internet, without anonymous technologies. Therefore it should be easy to track down the perpetrators.

The name of the ring is Instagram. You can view their recruiting page at instagram.com.

Yours truly, anonymous reporter"

I mean I would probably link the content, but that's just me.

Might want to try a different jurisdiction these days.

EU, Canada, Australia, Japan, f'rex.

I'm in Australia, so I kick it to the Australian Federal Police (FBI equivalent) via https://www.accce.gov.au/
