Total fear-mongering bullshit.
The key word here is "SUSPECTED"... they don't know. With millions of users on the platform they suspect 600 pics.
"found over 600 pieces of known or suspected child abuse material"
No one in their organization could look at 600 pics BEFORE they wrote the report?
This is not a serious group of researchers. They are obviously lying like hell.
Why do they suspect these 600 pics?
because “We got more photoDNA hits"...
in plain English that means their software flagged the photos. A robot said they are suspicious. Out of millions and millions of pics all over Mastodon 600 are maybe bad according to a bot.
Here's a link to the absolute shit propaganda:
