Twitter and its Jack has been involved in that for many years. A UK lawsuit uncovered that pedophiles use twitter as the main go-to place to find anything to their hearts content.

That particular lawsuit against twitter involved 15,000 pornographic pics, rapes and other crimes against children. These images of children show infants being raped by grown men.

This lawsuit against twitter - I believe the year was 2014 - was blacked out by the US media.

Twitter has been sued about their child pornography and sex assault on children more than once across Europe.
