One time I came across a github user with a username that started with a hyphen. I could browse their repos fine, but I couldn't view their github.io site on Linux. It turns out that Windows and OSX allow domain components to start with a hyphen, but Linux does not. There is at least one DNS RFC that disallows this though.
