Uh, that's not what was said at all, but you can read what you want. He said serious threats (which could include death threats) are deleted. He didn't say whether or not they were banned (which I presume they are) and he did admit that threads that deal with repetitive topics are closed down and redirected to one large thread that already discusses that topic. It's no different than here (although I think the threshold is lowered slightly when it comes to repetitive topics, I've still seen some locked down). And flaming and trolling posts get deleted (that's why they have the big red moderator action tags for).
