Comment Section Crashers: Why Dropping Your Link Is Never a Good Look

A few weeks ago, I posted something I was genuinely proud of on LinkedIn — a piece about how journalists verify sources in the age of AI-generated everything. Within an hour, it had a healthy stream of comments. People were debating, sharing their own war stories, asking follow-up questions. It was exactly the kind of conversation I love seeing under my own posts.

And then, right in the middle of it, someone dropped a link to their “AI-powered fact-checking tool” with zero context, zero acknowledgment of anything I’d actually said, and a caption that read like it was copy-pasted from their last 50 comments on other people’s posts (because it probably was).

I deleted it. I don’t feel bad about that, and I’ll explain why in a minute. When the person reposted it after I’d deleted it, I went a step further and blocked them. I’m not a fan of blocking people and rarely do it. In this person’s case, it wasn’t the first time they’d dropped an irrelevant, self-promoting link in my comments, so they earned the block.

If you’ve spent any amount of time on LinkedIn, you already know exactly the move I’m talking about. You publish something you worked hard on, the conversation starts humming along nicely, and then someone shows up with a link to their newsletter, their course, or their “game-changing” tool — with no relevance to what you said. It’s the digital equivalent of crashing someone else’s presentation to hand out your own business cards.

Let’s talk about why this behavior riles people up so much, and more importantly, how to promote yourself without becoming that person.

It hijacks their content and audience

When someone publishes a post, they’ve put in the work. They drafted it, revised it, hit publish, and probably held their breath for a bit hoping it would land. They’ve spent months or years building the audience that shows up to engage with it.

When you drop a self-promotional link into their comments, you’re essentially poaching that reach. You’re borrowing someone else’s hard-earned visibility for your own financial or professional gain, without contributing anything of value to the conversation they started. It’s not networking. It’s freeloading with a hyperlink.

It’s devoid of context (and value)

I read a lot of comments in my line of work. Partly out of curiosity, partly because I’m nosy, and partly because comment sections are a goldmine for understanding how people think. Most self-promotional comments look like spam because they have no genuine connection to the topic being discussed. The link might be tangentially relevant, but if you lead with a pitch instead of a point, you’ve already told everyone reading that you’re not there to engage, learn, or debate. You’re just treating someone else’s comment section as free ad space.

It signals “me, me, me”

LinkedIn bills itself as a professional networking platform, and real networking — the kind that gets you clients, jobs, or collaborators — runs on reciprocity. Dropping a link and disappearing signals that you care entirely about your own metrics and not one bit about building an actual relationship with the person whose post you just used as a launchpad.

I don’t know about anyone else, but I’m not interested in working with someone who puts themselves first in the relationship. That’s not how you serve clients (not if you want to keep them, anway).

It disrupts the conversation

A good comment section is a small forum. People are debating, adding nuance, sharing their own experiences. Self-promotional links derail that flow. They force the original poster to make an awkward choice: ignore it, delete it, or watch the thread get hijacked by something that has nothing to do with what anyone was talking about. None of those outcomes reflect well on you.

How to promote yourself the right way on LinkedIn

None of this means you should stay invisible. I’m not telling you to never interact and hope someone notices your brilliance through osmosis. What I am telling you is that the tactics need to change. If you want to borrow some of the energy from someone else’s high-traffic post — and there’s nothing wrong with wanting that — try one of these approaches instead.

· The value-first comment. Write a thoughtful, insightful response to their post. Add a real takeaway, a counter-perspective, or a detail from your own experience that adds something to the conversation. When you consistently show up as smart and generous with your insight, people get curious. They click your profile. They follow you. Nobody had to be pitched.

· The curiosity play. Instead of dropping a link to your own article on the topic, share a brief, compelling snippet or takeaway in the comments, then end with a genuine question that invites dialogue. You’re not selling anything in the moment. You’re demonstrating that you know what you’re talking about and that you’re interested in what other people think, too.

· Move it to your feed. If you have a resource that genuinely expands on their post, don’t hijack their comments. Share their post to your profile and add your unique thoughts. Tag the original creator and say something like, “Loved [Name]’s post today about X. It got me thinking about Y, which I wrote about here...” This gives credit where it’s due and drives traffic to your own page the right way — through your content, on your turf.

Pro-Tip: If someone specifically asks a question like, “Does anyone have a good tool or article for X?” share away. That’s not hijacking, that’s answering a direct question. Context is everything.

Why social media etiquette matters

Plopping an irrelevant link into someone’s comment section isn’t just an etiquette issue. It’s a branding issue. Every time you engage in this behavior, you’re doing more than annoying the original poster. You’re broadcasting to everyone watching that you’re the kind of professional who treats relationships as transactions. That reputation follows you. People remember who showed up to add value and who showed up to sell something.

I’ve built most of my freelance career on relationship-building the right way. Nobody has ever hired me because I dropped a link under their post. They’ve hired me because I showed up consistently as someone worth talking to.

LinkedIn, like any professional space, runs on trust. You wouldn’t walk into a networking mixer, interrupt someone’s conversation, and hand them your business card without so much as a hello. The digital version of that move is no less rude just because there’s a screen between you and the person you’re doing it to.

So, the next time you see a post that makes you think, “Oh, I have something perfect for this,” pause. Ask yourself whether you’re about to add to the conversation or hijack it. The difference between the two is usually obvious once you stop and look at it honestly — and it’s the difference between building a reputation people trust and becoming the person whose comments get deleted.
