I totally agree with this logic, but I think fiverr should ease the process to one 5 star rating per point, even beyond 4.7 stars.
Scammers are becoming rampant and your competitors can easily sabotage your fiverr career with a 1 star rating... This certainly isn't fair and it makes fiverr seem more like a gamble than an actual source of livelihood. You would never know when you'd be hit!
