hmm ok benefit of doubt given - refused every possible username and does not say what is wrong with them, did not appear to work, then did unexpectedly, then tried username recovery but got 404s. Genuinely I'd never heard of them before now so I was like - 'wait what is there something else going on? like some shell thing posted to hackernews'...
I just tried again and it completed and is working okay now - bit of a fiddly registration process but actual vpn seems to pretty good and there are lots of endpoints, so great too.
