In Voat's rules the line was crossed.

User agreement Do Not Incite Harm: You agree not to encourage harm against people. Protect Kids: You agree not to post any child pornography or sexually suggestive content involving minors.

In USA law which Voat is under a line was crossed.

https://en.wikipedia.org/wiki/Incitement#United_States - The First Amendment to the United States Constitution guarantees free speech, and the degree to which incitement is protected speech is determined by the imminent lawless action test introduced by the 1969 Supreme Court decision in the case Brandenburg v. Ohio. The court ruled that incitement of events in the indefinite future was protected, but encouragement of "imminent" illegal acts was not protected. This "view reflects longstanding law and is shared by the Federalist Society, the ACLU, the Foundation for Individual Rights in Education, and the vast majority of Americans, including most staunch free-speech advocates."

Finally Puttitout confirming Voat has in the past been contacted about 'threats' https://voat.co/v/Voat/3178819

https://en.wikipedia.org/wiki/Imminent_lawless_action - Advocacy of force or criminal activity does not receive First Amendment protections if (1) the advocacy is directed to inciting or producing imminent lawless action, and (2) is likely to incite or produce such action.

There is ZERO defense for this type of action, even more so when the target is children. There is no legal or moral justification anyone can pull out of their ass to deflect or protect anyone involved in these actions.

The line was crossed and they are going to keep pushing it until either action is taken against Voat or Voat is forced to take action against the clearly malicious accounts.
