In a recent answer, Juan M ♦ mentioned that "Lately, we have had an increase of resignation posts that have served to host combative and hurtful words to attack Stack employees, other mods, and teammates." as an explanation for why moderator resignation posts "will be featured for around 24 hours moving forward" but not deleted.

Several of the moderator resignation posts that I have seen contain strong messages that the resigning moderators in question no longer feel comfortable with Stack Exchange policies and/or culture, but I can't recall ever seeing one that has crossed the line from ordinary criticism to fighting words.

How often does hurtful speech actually appear in moderator resignation notices? Can anyone give any specific examples of moderator resignation notices that are sufficiently "combative and hurtful" to warrant removal of featured status but that are not immediately red-flaggable as violations of the Code of Conduct?
