alert, inform, notify, announce ..... that's what HN does.

How about refocusing your attention on the actual matter at hand.

That is, Linus calling out Kees for being actively malicous.

Personally, I would have contacted Konstantin privately to lock (at least temporarily) Kees account. Then I would have sought an explanation from Kees (on the mailing list), and waited for his response. And I would have done this before calling him out as being guilty of active maliciousness.

Of course Linus love drama (especially drama that he creates.).
