I think that article pretty much sums it all...
Viewers got their videos banned, they reported you and fiverr closed your account which led to your money loss.
Viewers should have been aware this could happen... I mean, who was thinking of getting 10k real views vs $5? hehe
Fiverr has the right to close your account and take the money earned, however, I think they should refund it to the people who purchased the order.
In either case, I think they will keep the money for themselves, as you have broke the social media TOS and received a ton of negative reviews in regards of your service.
Sorry to hear that, but it looks like Fiverr would have the winning hand here...
