You don't know how 4chan doxx works.

There is no doxx going on in /g/, you'll get banned for it.

Instead people embed links in images and posts right before threads necro to discord servers etc... And people who have too much time on their hands that frequent for example /g/ organize the doxx there.

I've reported and got enough of those taken down to say that it's very probable they actually did doxx.

Beyond that it they've filed a police report that instantly makes it quite credible.

Also I don't see why someone who doesn't use C professionally isn't allowed to fork it. Forking a project is more about building a community behind the fork than anything else.
