Yeah, contact details as far as I know aren't copyrightable nor under public domain. Things like your personal contact details though are subject to privacy violation laws if they are used without your consent, I believe. So nothing stopping from one publishing them, but if one asks to have personal detail taken down, they should be honoured without hesitation.
I've brought the issue to Github as well for them to judge whether there is any breach. They are best to decide I guess.
