Github is forcing me to change my username, and will not tell me why

Notice that there's seemingly no 'admin' user on GitHub.

Because people may be linking to your projects and changing user names will break those links.

Because the username "admin" is so much reserved that even an admin user can't use it.

That website fucking sucks. Hope they fix it some day.

Nowhere were I talking about a "jewish conspiracy", apparently your own obsessions cause you to project this hard. What I was mocking is the common use of the phrase "security concerns" akin to a piece of rag used to stuff someone's mouth shut (so as to, should they choose to argue their point further, make them look like a "threat" to the aforementioned "security").

If you own any domain names, let's see how you react when IANA revokes them someday because "hurr durr muh technical and security concerns kthxbai".

So everyone who registered with a username that is an actual word should fear that Github could make them give up that username any day if they choose to make a page about the subject the username in question commonly represents?

Nice bait.

Yes.
