How to change the Reddit Display SERPS on Google Serach?

I have a client (image is for reference). I am stuck and need some fresh ideas to suppressing or replacing these posts that are harmful to their business. I am calling this box a "Reddit Display" because I have no idea what else to call it.

They are influenced by Google SERPS not Reddit SERPS. I can't seem to get traction.

I have tried:

1. New posts with more comments
2. CTR manipulation on good posts
3. Backlinking on good posts
4. DMCA Takedowns on negative posts

Nothing is sticking or removing this top post, which has been there for over a year. This doesn't align with our suppression campaign tactics. I have successfully suppressed it on reddit but it's clearly getting the clicks even though most of these posts are archived.

I can dominate on Reddit, but this isn't following any of the rules that I know about.

I have gotten a small 3 week movement to one of my posts has 200+ comments where the other posts only have 40-60 comments. But it went back to normal. These posts are ranking for the company keywords on Reddit and I am tasked with suppressing this unique challenge.

Anyone success at this process and know what to do?



Not my client. and this gives you some idea of what I am talking about.

that reddit discussions box runs on its own ranking logic separate from regular reddit serps, comment count/recency matters less than actual engagement velocity google's tracking
