CommentRewarder. Although I have never used it (also relatively new I think), I was aware of it and it seemed like a pretty good idea, as my understanding is that it simply "backs / reinforces" how you upvote those who comment on your post.

That is one aspect of Hive which I found to be frustrating, as I (and others) do make a sincere effort to write good comments. There are plenty of authors who simply do not EVER reward comments. At least as far as I ever experienced ... This is not personal to me, as scrolling down through the comments on these authors, they never upvote the comments of ANYONE ... And their decision has nothing to do with the threshhold below which it does not count ...

• ^{Case-in-point: Reading through the link you provided, I see that FriendlyMoose chose NOT to upvote the comments on his TopComments intro post ... 🤷‍♂️}

I think that is a mistake, but ... To each their own ...

"I'm also taking some profits after 5 years on chain."

I am glad to hear that. I am very sorry to hear, however, if someone is downvoting your work, as a result. This "behavior management" aspect of Hive is what led to my divestiture.

Downvoting due to plagiarism, etc.? Fine? Simply to "drive" people in one way or the other? Not even close to fine AND damaging to the prospects of any investor (IMHO) ever taking the Hive blockchain seriously, since EVERYONE's stake gets hurt by this type of activity ...
