Are your competitors' LinkedIn engagers a lead source?
Yes, and it is one of the strongest public signals there is: someone commenting on a competitor's post is engaging your exact category, this week, in public, often naming their problem in their own words. Legally, the landmark hiQ v. LinkedIn litigation established that accessing public profile data does not violate the federal anti-hacking statute (CFAA), while also showing that HOW you collect matters: hiQ still lost on contract claims and shut down. The compliant play is to work public engagement signals through legitimate tooling and human outreach, never logged-in scraping or automation that violates platform terms.

The best-qualified strangers on the internet
Think about what a comment on a competitor's post actually encodes. The person has the problem your category solves, or they would not be there. They are actively paying attention to solutions, this week. And they told you what they think, in their own words, in public. No purchased list carries that combination of fit, timing, and context. With buyers picking overwhelmingly from shortlists formed before they ever talk to sellers, the people evaluating your category in public right now are precisely the ones deciding whether you exist.
Reactions are softer than comments, and both are softer than someone describing a pain point in a thread. Treat the engagement type as part of the scoring, not all engagers as equal.
What the law actually settled
The landmark case is hiQ Labs v. LinkedIn. In April 2022 the Ninth Circuit held that accessing publicly available web data does not violate the Computer Fraud and Abuse Act, the federal anti-hacking statute. That is the strongest judicial statement we have that public data is, in fact, public.
But the case's ending is the other half of the lesson: hiQ ultimately lost on LinkedIn's breach-of-contract claims over its collection methods (including fake accounts) and shut down. The durable takeaway for a founder: the SIGNAL is legitimate; the METHOD is where risk lives. Logged-in scraping, fake profiles, and automation that violates platform terms are how companies in this space die.
The compliant playbook
Watch competitor pages and the voices your shared buyers follow. Collect only what is public. Score engagers against your ideal customer profile so you work fits, not everyone. Then do the outreach like a human: reference the substance of what they said, never the surveillance ("saw you commenting on X's post" is both creepy and self-defeating), keep the first touches free of any pitch, and let a real reply or profile visit tell you when they are warm. One irreplaceable rule: your competitor's audience judges you by the same standard as everyone else, so your own content has to hold up when they check your profile, because they will.
Slingapult's read: competitor listeners are built in, and the posture is the point: public signals only, no logged-in scraping, no fake accounts, every message drafted for a human to approve. The intent boost competitor engagers get in scoring reflects what the signal really is: someone shopping your category out loud.
