@J12t At least in the EU the DSA is quite clear that hatespeak and criminal content is not covered by freedom of expression and social media companies have to remove it. Also the DSA only affects platforms with more then 45 million users locally (what would mean on one instance) so Fedi (except Threads probabbly) is off the hook here.
@pieselpriemel I assume any jurisdiction with free speech rights will have very similar issues to grapple with.
