It might be a good idea to make explicit rulings on some of the borderline sources.
If it were me, I would ban ScienceAlert, for example. "A Physicist Reveals Why You Should Run in The Rain" or "NASA Reveals Spooky Eyes in Space, And They're Staring Straight at You." They have a lot of good articles, too, but some of it is clearly just stuff for clicks. Psypost is also a little dubious. Maybe if it's something a scientist in that field would ever read and take seriously, including reliable journalism sources that are talking about science, then it's good, but if it would be viewed as pop-science clickbait, then we need to talk about it.
These are just ideas. I'm just saying that clarifying by name some of the things near the border, maybe after checking with the community, might be good.
Yeah. If there's an explicit list, then it's easy to extrapolate, too, if some source comes in that's not on the list. I'm sure there will be little disagreements about particular sources, but it's easier if there's a clear guideline to follow.
