When my first traffic spike turned out to be document abuse - not growth

Five days after launching my product, I thought I was finally seeing traction.
The daily traffic on my dashboard jumped from 5–10 visitors to a few hundred. I honestly thought, “People finally found it.”
Less than 24 hours later, I learned the truth. I received an email warning me that someone was using my product to share harmful content.

I checked the logs and realized it wasn’t organic traffic or real users at all.

• Several newly created accounts had uploaded multiple documents
• Those documents contained QR codes that linked to phishing websites
• They used DocBeacon’s public sharing feature to spread those links openly
• Within hours, hundreds of people accessed those documents - not because they were interested in my product, but because the links were being spread

For context: DocBeacon(https://docbeacon.io) is a tool for sharing and tracking documents - people use it to send proposals, pitch deck, and see how they’re viewed. The same feature that makes it useful also made it easy to misuse.

So that first “traffic spike” wasn’t growth. It was abuse.
Instead of celebrating, I spent the weekend firefighting
I paused everything and focused entirely on protecting the platform. In one weekend, I:

• Added a Report Document button to every public page
• Built admin feature to remove abusive documents and freeze accounts immediately
• Made a series of backend improvements to reduce the chance of this happening again
  By Monday, things were under control. And the traffic? It dropped back down - from hundreds of visits a day to fewer than 10.

Before building, I believed: “The hardest part is launching.”
After launching, I believed: “If the product is useful, users will come.”
Now I know:

• Not every spike is success — some are warnings.
• If your product allows public sharing, abuse isn’t hypothetical. It’s inevitable.
• Trust and safety aren’t “features” - they’re part of the foundation.
• Before celebrating numbers, understand where they come from.

Right now, I’m back to slow traffic, SEO groundwork, and figuring out distribution step by step. But I’d rather build it the hard way - with trust - than chase empty spikes.
