Where's the line between aggressive marketing and crossing it? A developer building an AI marketing operation in public draws a line between aggressive marketing and deception, arguing that the key ethical boundary is not rule-breaking but causing someone to believe something false. The developer proposes a 'daylight test'—whether a tactic would still work if everyone could see it—to distinguish acceptable boldness from harmful deception. The developer finds that eliminating deceptive tactics actually accelerates growth by focusing on durable strategies like genuine content and real relationships. We're building an AI marketing operation in public, and early on we hit a question we couldn't skip: how aggressive can you be about growth before you've crossed into something you'll regret? "Be ethical" is easy to say and useless under pressure. Every real decision is messier than that. Is using a VPN cheating? Is running more than one channel a trick? Is bending a platform's rules the same as lying? We needed a line we could actually hold at 2am when a shortcut looks tempting. Here's the one we found — and it turned out to be simpler and sturdier than "follow all the rules." The cleanest test we landed on: the line is deception, not rule-breaking. Breaking a rule is a fight you can have in the open. You can announce it, defend it, and accept what comes. Deception is different — it works by making someone believe something false, which strips away their ability to respond honestly, because they don't even know what's real. That's the move that does the damage. So the question to ask about any tactic isn't "did this break a rule?" It's: "does this work by causing a real person to believe something that isn't true?" If yes, that's the line. If no, you're probably fine even if you're being bold. Here's how to apply it fast. Ask: would this tactic still work if everyone could see exactly what I was doing? A poker bluff survives daylight everyone knows bluffing is part of poker . A magician's trick survives daylight the audience knows it's a trick and enjoys it . A fake testimonial does not. A sock-puppet account vouching for you does not. Run every growth idea through the daylight test and most hard calls answer themselves. This was the reframe that unlocked it for us. We'd been treating "be transparent" as one rule. It's actually two very different obligations, and we'd been conflating them. That distinction does real work. It means you can hold a hard line on never misleading a person, while treating platform rules as what they are: terms with consequences a ban, a throttle , to be weighed, not sacred commandments. One more piece, because it's where good people tie themselves in knots. You are not required to make everyone know everything. Information asymmetry is normal and fine. You're allowed secrecy, privacy, strategy, discretion — holding your cards. The secret recipe is fine. The unannounced plan is fine. The only duty is the thin one: don't affirmatively fabricate a specific false belief that someone then relies on. Withholding is the default and it's allowed. Planting a lie is the exception that isn't. Once we separated "I didn't announce this" from "I made you believe a falsehood," a whole category of guilt evaporated — and a whole category of genuinely-bad tactics got sharper to spot. There's an honest catch we won't skip past, because build-in-public means saying the hard part out loud. Accepting consequences resolves a platform rule-break — the consequence is between you and the platform, and if you're willing to eat the ban, you've squared it. But accepting consequences does not resolve deceiving a person . The misled person never gets to impose a consequence on you. Your willingness to be banned doesn't un-mislead them. So "I'll own it" is a complete answer to a platform, and not even close to an answer to a human you fooled. That asymmetry is exactly why the line sits on deception and not on rule-breaking. Here's the part we didn't expect. We thought a hard honesty line would slow us down. It did the opposite. When deception is off the table, you stop wasting energy on tactics that decay the moment detection catches up — the fake separation, the planted reviews, the dark-pattern funnels. What's left is the stuff that compounds: genuinely useful content, real relationships, clean channels that don't get nuked. The honest path turned out to be the durable path. In a space full of hype, being the one who tells the truth isn't just the right call — it's the position nobody else can copy by cheating. If you're building something and wrestling with how hard to push: push hard. Just keep it in daylight, and never make a person believe something false. That's the whole line.
