Illegal Life Pro Tip: Want to ruin your competitor's business?
Been there. It might be competitors. It might just be fraudsters looking to see what they can get for free from that otherwise useless stash of credit card numbers they stole or got on some forum from someone who did. Once your marketing hits the radar of one of these crews they will pass your service on to each other. As a merchant you need to develop your own fraud screening techniques or pay someone to do it.<p>(Pardon me if I am projecting from my past startup experience to yours in all my comments.)<p>I am not blaming the victim. But the industry is setup so the merchant is most responsible for detecting and dealing with fraud. And that is probably objectively not a bad call. You have all kinds of ways to detect who is doing this and ways to stop this. I hate this crime with a passion and cut it down from 5000&#x2F;mo to 50&#x2F;month at my first startup when it blew up on us. But it is true the credit card middlemen, having externalities the risk to you, don’t then innovate incremental tools for merchants that well. I was frustrated when I received fraudulent requests there was no third party I could report my suspicions of fraud to with a confidence rating (or check against other merchants suspicions). I did many years later see a service like that but now can’t find it.<p>I did just now find a pretty good list of merchant anti fraud tactics which had tricks nobody told me at the time but I had to figure out myself and were pretty successful: <a href="https:&#x2F;&#x2F;support.authorize.net&#x2F;knowledgebase&#x2F;Knowledgearticle&#x2F;?code=000002330" rel="nofollow noreferrer">https:&#x2F;&#x2F;support.authorize.net&#x2F;knowledgebase&#x2F;Knowledgearticle...</a><p>Good luck. These guys are persistent. In my case most of them were coming from poor countries where a dollar of fraud is worth a lot more of their time than yours. Until you stop them cold, they will keep coming.
