Judge's liability for reposting content in a chat

I was wondering, if a judge shares some video or other content in a group chat that others might find offensive or discriminatory, even if it was done outside of work and, seemingly, not in the status of a judge, can this lead to disciplinary action? Where exactly is the line between private opinion and professional ethics for judges? Just curious, because we communicate in different chats, and it's not very clear whether such a case as with the British judge could happen here too.
