I was just about to start a thread on this, but you’re quick haha!
I have to say, I'm not too fussed about the changes overall. I do think the editable reviews could be a little easier for buyers to exploit your services, though. Just a thought!
I've had a few experiences with buyers who were a little impatient. If you're sleeping and they ask you some questions after leaving a review and you don't respond quick enough, they might think you're ignoring them on purpose and threaten you by changing the review with the help of Fiverr support.
Luckily, Fiverr doesn't help with these things, but now that we have this feature, I feel like it'll be easier for these buyers to exploit your services.
But the great thing is that you can stop them from editing the review by simply leaving your feedback. What do you think?
