If the info was scraped from public Github pages then I think it's legal for Gitpay to use it, assuming they aren't violating the Github TOS.
That doesn't mean it's not a shitty thing to do, and I really think it should be a violation of the Github TOS to republish the information without the user's explicit consent.
This has come up a number of times, and I'm really surprised Github hasn't addressed it already. I don't care if people read my info on Github (that's why I made it public), but it's really sleazy to co-opt that information to automatically create accounts on other services for people.
