Okay, but that site is demand driven, and you get to chose your project. Fiverr is supply-driven and it is a completely different concept, but they could implement some strategies to lower the scam artists.
I don’t say that you can’t get scammed on the other platform, but in order to get scammed, it would be your own fault, by not analyzing your clients prior applying or accepting their interview invite. If I am correct there was one guy, that got scammed by a Fiverr seller, there was a thread here on the forum on that topic. It was obvious that the fault was on the seller from the other platform, as he accepted to work without a payment.
I had only one cancellation on the other platform, and it was due to my fault, of not vetting the buyer.
