I was gearing up to smugly quote the HN guidelines to you but I find myself surprised to see that there is no clear messaging against supporting acts of violence.
Allow me to violate the guidelines and note how this is in stark contrast to Reddit. For better or worse.
HN has issues with trolls, and trolls don't care about guidelines. Almost every time I read a comment that's clearly out of place it comes from a throwaway-like account registered like 4 months ago. And the comment history is full of such comments, so it's often not a one-off.
Despite this, HN doesn't do much about it, and creating new accounts and trolling for a couple of months is very, very easy.
