In fiverr sometimes you will receive a message from buyer telling you to do the business outside of Fiverr. He will give you the incentive that you will get the extra 20% which Fiverr charges if you do business through Fiverr.
If you agreed on doing business outside of Fiverr and exchanged email or any other contact information. The buyer will ask you to deliver work first then he will pay you. If you deliver the work. You won’t see the buyer again. You are scammed. When you return back to Fiverr, you will notice that your account doesn’t exists any more. You are blocked from Fiverr because you violate Fiverr TOS. It is against the rule to make a deal outsite of Fiverr.
Fiverr gets 20% but at least it is guaranteed money. So better let go 20% instead of 100% and your account.
