I would just point out that being "unintentional" does not excuse breaches of law, and rarely codes of behaviour of any kind. After all, almost anyone could claim a behaviour was unintentional, if that was all it took. But of course, the claim she was unaware of such behaviour bears little weight when Sir Philip Rutnam resigned after accusing her of being involved in a "vicious and orchestrated campaign". Even if she denies it, it would be reasonable if you were accused of it to wonder why people might think you were.
