Small tangent:In my school back in like 3rd they taught us that these were "never" reliable. Particularly of note is that they said the com TLD was "commercial" meaning they were trying to sell you something. Which is technically true, but in practice, no.
Also little me went nuts because they made no mention of .net.
I just think the idea of using a TLD alone to judge the credibility of a website is silly and the domain should only be used to see if you're on the website you think you're on
