If you have ever launched something on Reddit, you know the specific dread. Your thread is climbing, the replies are positive, and then it appears near the top: "This is a scam, don't buy." Maybe it is a competitor, maybe a troll, maybe someone who confused you with a different company. It does not matter. That comment is now the first thing every potential customer reads, and it is quietly costing you conversions in real time.
Here is how Reddit's comment ranking actually works, why a single negative comment does outsized damage, and how to push it out of view without leaving a mess.
How Reddit's comment collapse threshold works
Reddit automatically collapses comments that fall below a certain score — usually around -4 or -5. Once collapsed, the comment body is hidden behind a grey "comment score below threshold" line, and a reader has to click to expand it. Most never do.
The exact number shifts a little by subreddit and by each user's own settings, but -5 is the universal safe target: at -5 a comment is collapsed for virtually everyone. If you want the precise number of downvotes it takes to get a specific comment there, our free comment burial calculator works it out from the comment's current score.
Why one negative comment does so much damage
It owns the first impression. Most people skim only the first few comments. If three are positive and the fourth says "this is a scam," the scam comment is the one they remember.
It grants permission for the pile-on. Reddit is a crowd. A critical comment with a couple of upvotes signals that criticism is welcome, and a thread can tip from positive to hostile quickly.
It lives in Google for years. Reddit threads rank in Google's "Discussions and forums" block and get quoted by AI assistants. A damaging comment inside a well-ranked thread becomes a permanent line in your search results long after the thread has gone quiet.
Organic defence vs. burying it
You have two honest options when a bad comment appears.
Reply and hope. Respond politely, ask for specifics, and hope reasonable readers upvote your reply above the criticism. This sometimes works — but it is slow, and while you wait, the comment keeps converting visitors into lost sales.
Bury it with downvotes. Push the comment below the collapse line so it drops out of the default view. This is immediate and, done properly, invisible to everyone else.
How to bury a comment safely
The thing that gets people caught is speed. A comment dropping from +12 to -20 in two minutes is obviously staged; Reddit may freeze the comment's score, or real users may upvote it back up out of spite.
A safe burial uses aged accounts on unique residential IPs, voting at a pace that matches the thread's natural rhythm. The comment drifts from +12 to +6 to -1 to -5 over an hour or two, and by the time it is collapsed, nothing looked unusual. That is exactly what our delivery engine is built for: buy Reddit downvotes from $0.005 each that bury spam and bad-faith comments without a detectable footprint.
One note on judgement: this is for suppressing spam, scams, and misinformation about your brand — not for silencing honest criticism. Genuine negative feedback is worth answering in the open. Save the downvotes for the comments that are actually lying.
