Requiring a review before release requires a rather large change to how the current system works, adding more centralization, and slows down how quickly new threats can be blocked. This event took two days to notice and be changed, and that's for a list with a relatively low amount of users. The current method seems fine.

I learn things of value when reading materials from opposing points of view, even if the opinion or spin is extreme. I think it’s a valuable and important exercise, but, as you say, probably best when you have your wits about you.

As needed filtering is certainly best.
