I signed up and immediately got banned because I was accessing through a VPN, which I think is a common problem others have had. I emailed them and their advice was to stop using a VPN and try again.
Perhaps they could implement some way to do a 1-cent bank transfer from an account with a name which isn't on their fraud list, but as a simple step it seems pretty normal to use your regular internet connection (that ties the IP+timestamp combination to a real-world subscriber) and not some anonymity service
Although it would be nice if we could be anonymous on the web, when abuse traffic is involved (more than posting a comment on some forum as an anonymous source or something), I don't know how that'd be possible to reconcile
I don't want any business critical infra managed by a company willing to be that aggressive in blocking accounts, while also having slow customer service to resolve access issues.
Then it worked, and I've had no problems since. I'm concerned about them failing to charge my virtual debit card some month in the future and losing data, but it hasn't happened yet.
If there was anything else nearly as cheap, or if it wasn't for personal use, I probably would have given up and used another service.
This isn't particularly common, but it's not uncommon either.
