For loshon hora, so if you do this unintentionally, it’s an ????? ?????. It would, ?????, require teshuva like any other aveira b’shogeg, and once the teshuva is done, a person returns to being a beinoni.
The difference between ?????? ???? and ???? ??? is that the first is only in a person’s ?????, which is not fully under the control of a beinoni, while ???? ??? is much closer to a ???? than a ?????. (Although, it would be an interesting side topic to explore whether ???? ??? is different between ???? is not quite the same as a ???? ???? for all things).
