You posted a YouTube Short, and within minutes the comments are rolling in. Exciting, right? Then you actually read them. “Nice content bro check my channel.” “Great video! I subscribed, sub back?” “🔥🔥🔥 follow me.” Your stomach drops. Those aren’t real viewers — they’re bots, and they found your video faster than any human possibly could. Here’s the thing that makes this even more frustrating: YouTube Shorts receives over 70 billion views per day, according to Google’s own announcements, and that massive traffic volume is exactly what makes it a magnet for spam accounts.
Why Do Bots Target YouTube Shorts Specifically?
Shorts attracts more bot activity than regular long-form videos, and there’s a clear reason for it. Bots are programmed to find content that’s getting early traction — fast. Because Shorts are served through a scrollable feed (similar to TikTok), new videos can get thousands of impressions (that’s the total number of times your video appears on someone’s screen, whether they click it or not) within the first hour of posting. Bots are scanning for that early spike and jumping on it immediately.
Spam comment operations typically run automated scripts that search for recently uploaded Shorts with rising view counts. According to a 2023 report by cybersecurity firm CHEQ, bots account for roughly 40% of all internet traffic — and content platforms are one of their primary targets. YouTube Shorts, being one of the fastest-growing content surfaces on the internet right now, gets hit disproportionately hard.
There are usually three types of spam comments you’ll see on Shorts:
- Sub-for-sub bots — accounts asking you to subscribe back, often pretending to be real creators
- Promotional spam — accounts dropping links or channel names hoping to piggyback on your visibility
- Engagement bait bots — accounts leaving generic praise like “amazing content!” to appear human while building up their own comment history
Takeaway: Bots target Shorts because of the rapid early exposure the format gets — your video doesn’t have to be viral for them to find it. Even 200 views in an hour is enough to trigger automated spam scripts.
Does Bot Spam on Shorts Actually Hurt Your Channel?
Yes — and in more ways than most creators realize. The damage isn’t dramatic or sudden, but it compounds over time in ways that genuinely slow your growth.
First, there’s the credibility problem. Real viewers who land on your Short and see a comment section full of obvious spam are less likely to leave a genuine comment themselves. Comments are a signal of community, and a polluted comment section makes your channel feel low-quality even if your content is excellent.
Second — and this is the part most beginners don’t know about — YouTube’s algorithm uses engagement quality as a signal, not just engagement quantity. YouTube has confirmed in its Creator Insider videos that it can detect patterns of low-quality engagement and that this type of activity doesn’t help a video’s distribution. Spam comments don’t count toward meaningful engagement metrics, and if the accounts leaving them are eventually flagged or removed by YouTube, you could see your comment count drop significantly, which can look suspicious on your analytics.
Third, some spam accounts aren’t bots at all — they’re real people using spam tactics who will also leave dislikes or report your content if they don’t get what they want (like a sub-back). That kind of interaction is actively harmful.
According to data from Social Blade, channels with consistently low comment-to-view ratios (a sign that comments aren’t coming from genuine viewers) tend to plateau faster than channels where the ratio is healthier. A healthy benchmark to aim for is roughly 0.5–1 comment per 100 views on Shorts — lower than long-form, but it should still be real engagement.
Takeaway: Spam comments don’t just look bad — they can dilute your engagement quality signals and make real viewers less likely to interact with your content.
How to Fix Bot Comments on YouTube Shorts: Your Step-by-Step Options
Here’s the good news: YouTube has built several tools specifically for this problem, and most creators don’t know all of them exist. Here’s exactly how to use them.
Step 1: Turn On Held-for-Review Comments
This is the single most effective setting for filtering spam before it goes public. When you enable “hold potentially inappropriate comments for review,” YouTube’s own spam filter catches most bot comments and puts them in a queue only you can see — they never appear publicly unless you approve them.
- Go to YouTube Studio
- Click Settings in the left sidebar
- Click Community
- Under “Automated filters,” check the box that says “Hold potentially inappropriate comments for review”
- Also check “Hold all comments for review” if spam is extremely heavy — though this means approving every comment manually
YouTube’s spam detection catches a significant portion of bot comments automatically when this setting is on. Most creators who turn this on report seeing 60–80% of obvious spam disappear from their public comment sections within 24 hours.
Step 2: Use Blocked Words to Filter Specific Spam Phrases
In that same Community settings page, there’s a “Blocked words” field. Add the phrases you see repeatedly in your spam comments. Common ones to start with:
- “sub for sub”
- “sub back”
- “check my channel”
- “follow me”
- “grow together”
Any comment containing those exact phrases will be automatically held before it appears publicly. You can add up to 500 blocked words or phrases.
Step 3: Enable Comment Moderation Directly on Shorts
You can also restrict comments on individual Shorts if a particular video is getting hammered. Go to YouTube Studio → Content → click the Short → Details → scroll to “Comments and ratings” and change the setting from “Allow all comments” to “Hold all comments for review.” This is useful for Shorts that suddenly go semi-viral and attract a wave of spam.
Step 4: Report and Block Spam Accounts
When you see spam comments, don’t delete them — report them first. Click the three dots next to the comment, select “Report,” and choose “Spam or misleading.” This sends a signal to YouTube’s moderation system and helps train it to catch similar accounts faster. After reporting, then delete. This extra step genuinely helps the platform’s ability to catch spam, and it’s confirmed by YouTube’s own Help documentation.
Takeaway: Start with the “held for review” setting in YouTube Studio → Settings → Community. That one change alone will stop most spam comments from ever appearing publicly on your Shorts.
What About Third-Party Tools for Managing Spam Comments?
A few tools can help, though none of them replace YouTube’s native filters — they work alongside them.
TubeBuddy (a browser extension for YouTube creators) has a comment filter feature that lets you bulk-delete comments matching certain patterns. If you’ve got hundreds of old spam comments already on your channel, TubeBuddy can help you clean them up faster than going one by one. Their free tier includes basic filtering; paid plans (starting at around $4.99/month) unlock bulk actions.
vidIQ also has comment management features and flags suspicious engagement patterns in your analytics. Their free version gives you enough visibility to spot if a particular Short is attracting abnormally high spam activity compared to your other content.
One thing to be clear about: avoid any third-party service that promises to “remove bot comments automatically in real time” without being an official YouTube partner. Some of these services require your YouTube account credentials, which is a serious security risk and violates YouTube’s Terms of Service.
Takeaway: TubeBuddy is the most practical third-party option for cleaning up existing spam. For ongoing prevention, YouTube Studio’s native filters are your best tool.
How to Tell Real Comments From Bot Comments (When It’s Not Obvious)
Some spam accounts are more sophisticated than basic “sub for sub” bots. Here’s how to spot them:
- New or empty accounts — Click on the commenter’s profile. If their channel has zero videos, no profile picture, and was created recently, it’s almost certainly spam.
- Generic compliments with no specifics — A real viewer of a cooking Short might say “I never knew you could do that with garlic!” A bot says “great video keep it up!”
- Identical comments across multiple videos — If you see the same account leaving the same comment on your last five Shorts, that’s automated behavior.
- Accounts with unusual subscriber counts — Spam accounts often have 0 subscribers or suspiciously round numbers like exactly 1,000 subscribers with no view history.
When in doubt, report and remove. You’re not going to accidentally ban a real fan — real fans don’t leave content-free compliments on every single video you post within seconds of uploading.
Takeaway: Click on the commenter’s profile before deleting. An empty channel with no videos and a generic username is almost always spam — report it before you delete the comment.
Getting Real Engagement While Keeping the Spam Out
Here’s a reality check: bot comments are partly so annoying because they show up when real engagement feels harder to come by. If your Shorts are getting spam comments but not many genuine ones, that’s a separate problem worth addressing. Real engagement on Shorts comes from content that creates a reaction — a question at the end of your video, a controversial take, a genuine moment of surprise. According to YouTube’s Creator Academy, Shorts with a clear hook in the first 2 seconds retain significantly more viewers through to the end, and higher completion rates lead to more genuine comment activity.
If your Shorts are growing but you’re in that frustrating early phase where the algorithm hasn’t picked you up yet, it might be worth looking into what Flintzy’s YouTube promotion service offers. It’s built specifically for creators in the 0–10k subscriber range who need their content in front of real viewers — not bots — to get that initial momentum going. Getting real views early is what tells YouTube’s algorithm your content is worth pushing further.
Right now, open YouTube Studio, go to Settings → Community → Automated filters, and turn on “Hold potentially inappropriate comments for review.” That’s the most important fix for bot comments on YouTube Shorts, it takes under two minutes, and it’ll make a visible difference before your next Short even goes up. If you’ve already got existing spam in your comment section, spend 15 minutes reporting and deleting the worst offenders — your comment section is part of your channel’s first impression, and cleaning it up is worth the time.
