Thanks. I didn't know about X-Content-Type-Options! It is getting harder and harder to know all these headers nowadays. I am big fan of these checking tools with scores, it makes web developing entertaining. (A+! https://securityheaders.io/?q=https%3A%2F%2Fsatoshicrypt.com... )
I agree, I love these sorts of things because they make it easy to learn what you don't know. On the other hand, assigning an order based on an analysis like this can be interpreted wrongly, which I find annoying.
