I disagree there Mark sorry. I actually had an instance of a buyer leaving negative feedback. I left my feedback for him, and after 4 or 5 more positive reviews, my feedback for the negative man disappeared. What was that about I've no idea. That means none of the potential buyers had my side of the story. While it's been close to a year now since this happened, it still annoys the heck out of me. And, it's really not fair. When potential buyers go looking, and some do go looking for the negative marks, they won't be able to see any of the negative feedback I gave because they're gone... into the Fiverr Wasteland.
As for the issue at hand:
I am not keen on giving free work. Believe me, it's the bane of my existence as I rely heavily on Fiverr to pay my student loans, hospital bill and food in my house. However, if I feel a buyer is going to leave negative feedback, for no real good reason - extortion, unreal expectations or whatever, I do feel that a seller should have the right to cancel to avoid it. Buyers already have enough say around here without taking away this one thing sellers can do to "protect" themselves. IMHO! And, it does show up in the cancellation rate so potential buyers can use this to weigh into their decision.
