Be careful with fiverr reviews.
Today I faced with negative review deletion. There are ability to delete negative reviews ( don't know which side, but fact that it is not there ).
Long story short: As reseller I ordered from service provider and asked for specific requests. The requests wasn't done ( Client - always right? yeah... right,... not on fiverr ).
For the second order I insisted for requirements to be met., in result i was insulted and my site was chased and bad reviewed.
Another strange thing i noticed is that once i tried to access offer from service provider , it says "That seller is no longer available". But if you check the offer in incognito, you will see it perfectly without any problems... ( almost - sometimes fiverr crashes )
Anyway
In result if you had bad experience - its only your problem and fiverr doesn't wants to share the experience with other visitors - its bad for their reputation and money. Same as youtube's dislike button about to delete. Who wants bad thoughts when you can get only good ones....
p.s. Once we see all bad reviews on user thesibyl which insults clients, the post might be deleted.
