CitizenErased: This is the response I received from Flip support:
You'll need to contact the domain host of the website you're trying to access, to request them to unblock our customers IP ranges. IP Range: 103.9.40.0/22 103.224.128.0/22 163.47.104.0/22
That sounds, quite honestly, like nonsense. Why would fiverr or their host block flip or indeed any ISP in nz?
