Is it possible to have a designated flair that does not post to Hot/Trending/Popular page?

Application: We will periodically get posts on r/pregnant discussing loss in utero or terminating for medical reasons. The mom/parent absolutely does not take the decision lightly and are coming to our group to find support. However these posts will sometimes become so upvoted that they trend on the Hot/Popular page. Unfortunately, random people who hold certain views find the need to comment on these posts further guilting/shaming the mother/parent - "Why are you not fighting for your baby?" Or "You're going to murder your baby just because they have no lungs?"

The comments from non-followers are filtered out by our Crowd Control, but for some reason these people feel so passionately that they also chat and message the user, harassing and shaming them for their difficult choice.

Of course, we encourage these users to report the chats/messages when they reach out to us in modmail.

But I'd love to "save" these folks from the general masses on the Popular page. Is that possible?
