The people who need this almost never describe themselves as looking for Reddit marketing. They show up as someone whose post just got removed, or asking how to promote without getting banned, and they're saying it in public on the same platform you already work on. That's your list, and it refreshes every day without you paying for it.
We find our own leads the same way. Watch for the sentence that means somebody has the problem right now, not the keyword that means they're shopping. It usually reads as a complaint rather than a request.
The harder half is trust, since renting accounts means handing your promotion to a stranger. What closes it isn't a pitch, it's evidence: one placement you ran, what it did, and what you refuse to touch. Saying no to niches you can't post in safely is what makes the yes worth anything.
