Their intention is good trying to keep out blatant spam and misinformation. Being confidently incorrect is basically a running joke on the rest of Reddit. But they could be about 75 percent as draconian as they are and still be fine.

That said, I'd be careful saying the sub can't be "trusted." It's annoying but when you do get an answer it's generally sourced and credible. As opposed to the unadulterated bullshit I've seen on the rest of the site regarding basically anything I have professional experience and/or formal training in.
