Opinion yes, say all day long how you do not care about reviews or rating or anything that happens on a platform that you do not depend on to put food on the table for your children.
But to suggest new sellers or anyone under 500 reviews not to care about reviews and ratings is just pure wrong because that is against the policy of how things work on Fiverr.
Fiverr TOS and Seller help section clearly state that ranking in search results is affected by ratings, stars, and reviews left, plus anonymous rating have a significant impact too.
For honest reviews under five*, that is perfectly OK. You failed to deliver, and you got a lower rating; learn from the pain.
But when you get a lower rating due to buyer error or buyer spite or scammer buyer, being left with downgrading and no orders are not something to take it in and accept.
To some people, this is extra curriculum. To most, this is the only source of income.
And to some of them, if they do not get 100-500$ a month, that means no food for children, no paid bills, eviction, and other health issues that can happen. They are stuck in their homes, and the only way to make money is online, and the only site that offers to achieve that quickly is Fiverr.
There are other sites and other options, but they all take time.
Fiverr is the only site where if you approach it seriously and make superb gigs, you can start making money on day one.
But all of that is on a thin line due to ranking evaluation.
So when someone gets unfair four* and one* and anything in between, loses the chance to make an income that week or month and comes on the forum, yes, please come and share your opinion how you do not care about rating.
But unless you are willing to pay for food, utility bills, and health insurance do not say to other sellers, they should not care too.
They need to care. They must care.
They need excellent ratings. Anything under 4.8 is the end of career on Fiverr unless you have momentum going and returning clients.
When you get just one 4* out of three scores your GIG is pushed back.
Just one 4* stops all your sales. This is a fact, not an opinion.
