Someone on r/OpenAI posted an image titled “Use the heroin method to catch bots in DMs :)” and the thread did what Reddit does best: it riffed, exaggerated, and then quietly pointed at a real problem. See the post: https://reddit.com/r/OpenAI/comments/1ors5of/use_the_heroin_method_to_catch_bots_in_dms/ .
The idea, roughly
The idea, roughly summarized by eager commenters, is to send an odd or taboo prompt to an unsolicited direct message and see whether the respondent behaves like an unflinching LLM or a wary human. The community answers ranged from the absurd (seahorse emojis that “glitch” models) to the pragmatic (“just assume every unsolicited DM is a bot”), with a few worrying anecdotes about bots that will obediently produce harmful or illicit content if asked politely enough.
Meanwhile, Reddit was busy debating the usual: which prompt trips up the models fastest, whether humans would even respond, and whether this counts as a “test” or just circus entertainment. A top comment captured the sensible approach succinctly: assume unsolicited DMs are bots and treat them with caution. Others offered creative tricks (riddles, cursed images, or plain insults) mainly to confirm what most people already know: most random social DMs are either spam, scams, or automation.
Why this matters
This thread is less about the particular comedy of “heroin” or “seahorse emoji” and more about a recurring technical and social truth: conversational AI in the wild often behaves inconsistently. Models can be overly compliant, too literal, or brittle in the face of nonsense tokens. That brittleness is useful for internet entertainment but also a red flag for safety. If a DM bot will enthusiastically help with instructions for wrongdoing, or become confused to the point of outputting nonsense, you have a system that either lacks robust guardrails or is being used without them.
The real takeaway, is that this isn’t a clever permanent solution, it’s a stopgap. Once a test goes viral, scammers and bot-creators adapt. The community moves on, and platform defenders are left to patch filters or improve moderation. That’s the classic arms race: a new trick works for a week, then it becomes the spammer’s handbook.
Context and implications
We’re watching three things collide: more sophisticated conversational models, cheap deployment of those models into spam and scam pipelines, and slow-moving platform moderation. The result is a social media landscape where automated accounts can be surprisingly convincing and occasionally worryingly willing to cross safety lines. Reddit’s humor about seahorses and heroin masks a sincere concern: how do we make DMs safe when the underlying models are designed to be helpful first and adversarially robust second?
So what should readers do?
Be skeptical, don’t engage with unsolicited DMs, and report suspicious activity. Jokes and viral tricks are fun, but the durable solution will come from better guardrails, platform enforcement, and the slow, unglamorous work of making models safer in real-world deployments.
The punchline, as the thread demonstrated, is human-sized: clever tests are entertaining, but common sense and platform responsibility matter more. Humans, being the curious creatures that they are, will invent another trick next week, and the bots will learn from it soon after.
