I'll bet if you came up with an email chain that didn't make it obvious you were aware the autoreply was going to reply with '💩' you could absolutely get one that'd be actionable

Like spend a few paragraphs asking about protected classes or something, then respond with a "clarifying question" regarding the company's stance on said protected classes lol

At minimum Chief Twit will have to add a 'the above was autogenerated, this email is not from a person...' disclaimer
