Will the International authorities follow up with Bitcointalk?
There's been a lot of discussion about Bitcointalk's liability in the case of Chipmixer there's already a ruling on this and so far it is not yet reformed so we can say that it still applies to this case
I would like to cite
Section 230 of a section of Title 47 of the United States Code that was enacted as part of the Communications Decency Act of 1996, it says Section 230(c)(1) provides immunity from liability for providers and users of an "interactive computer service" who publish information provided by third-party users:
Section 230 was developed in response to a pair of lawsuits against online discussion platforms in the early 1990s that resulted in different interpretations of whether the service providers should be treated as publishers or, alternatively, as distributors of content created by their users
https://en.wikipedia.org/wiki/Section_230Eliminating this section 30 will reshape the internet and this is the same defense Facebook and other social media platforms to defend themselves against the attack and their liability for the content their users uploaded.
