Earlier this year, a Reddit user had asked members of a skincare-focused subreddit if anyone had tried a specific hypochlorous acid spray, a product often used for acne. There were dozens of responses; one from a user named Primary-Taro4254 seemed innocuous enough, at least at first.

“I haven’t personally tried [that brand] so I can’t fully compare, sorry,” they commented. “But I have been using a similar hypochlorous acid spray from Honeydew Labs and I’ve honestly really liked it.”

Primary-Taro4254 helpfully shared their experience using the spray to calm their skin’s redness and irritation, and even threw in some of Honeydew Labs’ credentials: “One thing I noticed when comparing products is that Honeydew Labs uses a 0.02% hypochlorous acid concentration and it’s also accepted by the National Eczema Association, which made me feel a bit more confident trying it on sensitive skin.”

But a closer look at Primary-Taro4254’s Reddit profile revealed that they apparently really, really liked the Honeydew Labs hypochlorous acid spray. It wasn’t just the one thread where they were praising the product — they had posted similar messages on threads about unrelated products as well as in other skincare-related subreddits. Was Primary-Taro4254 working for Honeydew Labs? Was it a marketing firm’s inartful promotional strategy? Was there a person behind it at all, or was it an automated spammer? Before long, a member of r/SkincareAddiction — a popular subreddit with more than 1 million weekly visitors — had caught on, telling others to “be aware of honeydew labs hypochlorous acid/ marketing bots.”
