The Supreme Court said that in order for a government official to be deemed as acting within his or her office as opposed to behaving online as a private individual, he or she must have “actual authority to speak on behalf of the state on a particular matter.” In such cases, government actors are “purporting to exercise that authority in the relevant posts,” and are thus not allowed to block dissenters.
