Not Embarassing Others -- Social Media

I just posted on the Other-Focused Orthodoxy - Mevaqshei Tov veYosher
group on Facebook:
    Two shiurim by Rav Yonatan Ziring should be required reading for any
    Jew who wants to be both Torah observant and a user of social media.

    Shiur #22: The Dangers of the Shame Storm - Public Humiliation in
    Halakha Part I
    https://www.etzion.org.il/en/shiur-22-dangers-shame-storm-public-humiliation-halakha-part-i
    ...
    Shiur #23: Cyberbullying - Public Humiliation in Halakha Part II
    https://www.etzion.org.il/en/shiur-23-cyberbullying-public-humiliation-halakha-part-ii

Rabbeinu Yonah's position (discussed there) is that Tamar's protecting
Yehudah was halachic, rather than lifnim mishuras hadin. Hamalbin
penei chaveiro is a kind of retzichah, and therefore included in
yeihareig ve'al ya'avor.

So I was wondering... Would Rabbeinu Yonah go so far as to say that
a Ben Noach who knowingly embarasses another is chayav misah?

Gut Voch!
