I say this every time but I’ll say it again. Find where your work is being used online and request its immediate removal because of non-payment. End users of content don’t do chargebacks. Resellers and middlemen do. They don’t try to get their money back immediately as they know that their account will get banned. This is why they wait.
Worse, you can guarantee that if you have lost $2,500 overall because of chargebacks, you are probably being taken for a ride over and over again by the same reseller operating under a new account identity.
My most successful countermeasure to a similar situation was to look at my chargebacks, find out where my content was being used and guess what? Both websites had been created by the same web design company.
I contacted both sites, both immediately removed my work and I’m guessing that both went all guns blazing after the people who were supposedly in charge of their web marketing.
I can not stress how important it is for people to do this. My first chargeback came from a buyer who had a profile showing they were based in Cyprus. My second a few months later showed that the buyer was based in the UK. They were, however, the same person and if I hadn’t put my foot down, I’m pretty sure that I would have kept on having chargeback after chargeback.
There is a culture of people who make it their business to never pay for services on Fiverr. This being the case, anyone who ever does this deserves the biggest and most unapologetic slap in the face that you can give them.
