"Organization owners now have the ability to block abusive users from public repositories. This feature allows project owners to block users, and prevents blocked users from opening or commenting on issues or pull requests, forking repositories, and adding or editing wiki pages."

I get blocking users from opening/commenting/sending PRs/editing the wiki, but why block them from forking a public project?

That seems very, very dangerous to me. I think GitHub needs to preserve the ability for anyone to fork a project.

That bothers me, too. This could be used to prevent forking.

They're not blocked from logging out and cloning the project, just from hosting it on GitHub as a "fork" linked back to the original project.

Yes, but why?

Because you don't want a MikeeUSA dragging your project's name through the muck and mire.

If you don't want people to be able to use your work how they wish, don't license it as free software. Or trademark the name if the naming is an issue. Blocking someone from being able to use your code is anti-software-freedom and goes against the spirit of the licenses most likely used by 99% of github repositories.
