Hi,
I am investigating phishing scams of crypto on social media sites .
Which authorities do Facebook, Twitter etc report these scams to once they have been flagged by users?
Surely on cyber related crimes/fraud bodies or any related institutions. Just didn't know the exact name. You can contact Facebook or Twitter on that concern.
But no need to go on authorities. Since you are targeting social media site, you can direct report it to them. It's way less hassle.
If found outside social media, you can report it on any web search engine companies so that they can filter the web result while at the same time forwarding the report to the authorities. One example is
https://safebrowsing.google.com by Google. Or you can seek an assistance at your local authorities about the concern.
