What are you not mentioned in your Good and Right Comment is that : Fiverr is an incredible platform and We PAY To use that. ( 20 % + Fees of every order ) . That make you and Fiverr in a contract. This is not my shop, this is like a Corporate. I pay for a Service, NOT just the Client.
And I don't want to mention here the question about the intellectual property because I understand that there is a lot of differences country by country.
As I said, I'm totally fine on how Fiverr work. But stand there saying "Everything is Perfect here, you are the only reason your profile is going wrong" sounds not positive at all, and I think that is your attitude, being positive. And i'm totally positive too.
Just try to think about that : When you pay a service , with taxes or with a fixed price, you are a Client too. Fiverr ( like everything ) is something can be better. Saying otherwise is not positive, is negative.
