The website is linked above if you wish to visit it.
Anyway I'm highly skeptical of the validity of this website and many of its potential mistypings.
If you think someone is mistyped mention who they are and what you think their real type might be.
I will mention at least one that I know for sure is mistyped and that is Baruch Spinoza. They have him typed as INFJ though I would think if he is not INTP then nobody is. Why? Because his entire book called "The Ethics" revolves completely around logical axioms and well defined categories which is about as Ti as someone can possibly get, not to also mention that Spinoza was Einstein's favorite philosopher and Einstein is the INTP poster boy. Let me prove their striking similarities in ideology as well as personality via videos below:
