After the updated review system. I have noticed that sellers' accounts are getting flagged without any fair reasons (Check out the link below).
My cousin visited me on his summer vacations and I told him about Fiverr. He was interested so we made an account for him.
Now after 7 or 8 months he wanted to buy my editing services because he was thinking of starting a Youtube Channel so he placed an order on my gig.
Fiverr cancelled that order, banned his account with his money still being in that account and gave me a warning while flagging my account.
When I contacted support and explained them this whole situation they said that their decision is final and now there is nothing they can do about it.
