Need advice on knocking down Reddit post off SERP.

I’m looking for practical, experience-based strategies to demote a specific Reddit thread that ranks prominently for my brand/keyphrase. I want approaches that work in the real world (not speculation) and that avoid illegal or abusive tactics.

Here’s the situation: the Reddit post is on a public subreddit, indexed by Google, and appears on page one for searches using our brand and product name. It is not copyright infringement, but it is damaging to our reputation and we need it to stop being visible to prospective customers.

So far I’ve tried politely contacting the poster, flagging the post to subreddit moderators, and filing a formal removal request with Reddit without success. I have not pursued legal action. I’m interested in hearing what has demonstrably worked for others: DMCA or legal routes when the content is not literally infringing, outreach to moderators/admins, using Google’s removal tools in meaningful ways, and most importantly, proactive SERP suppression via high-quality countercontent, targeted link-building, and authoritative property creation.

If you’ve suppressed a Reddit result before, what tactics moved the needle (type of content created, domains used, link/PR strategy, timelines, costs, and metrics you tracked)? Are there pitfalls or moderator policies I should be aware of when escalating? I value pragmatic, transparency-first methods and would appreciate case examples or stepwise frameworks that delivered measurable SERP movement.

Create more Reddit posts on you but with a positive tone, have you tried that?

Create and promote better content that outranks the Reddit post.
Use your own site, YouTube, Medium, LinkedIn, and trusted news or PR sites to publish SEO-optimized articles about your brand.
Build backlinks to these pages and keep them active on social media.
Ask Google to remove the Reddit result only if it violates their policies.
Focus on consistent, high-authority content to push the Reddit link off page one.

I once created a fake Reddit thread with the same title but neutral tone, Google swapped them in SERPs after heavy linking.
