GitHub provides an invaluable hosting service. Like all hosting platforms, any interaction between the content owner — the maintainer — and their community— the users — is owned exclusively by the owner. If you visit my repositories on GitHub, you are visiting my property, hosted generously by GitHub. It is not public space.
I wonder if the reframing by the IndieWeb community of hosting things on their own sites will prevent this sort of rudeness in the future, or will the social construct fall down with the influence of spammers and trolls?
