Looks like you guys are not aware of phonetic domains. You won't believe how professional social engineers can easily troll you. They can clone "apple.com" into "apple.com". See, does it make any changes? No, not here. Neither in URL box(unless you look very closely and investigate hard to know if its real). A hacker can register a domain name with phonetic technique where he can register apple.com(not real one, but with same text by some deep techniques on which I am going to write article soon). As @deanhills said the comma thing, yup, it can be more worse then a comma.

Didn't understood it yet? Let me show you real examples.
xn--pple-43d.com
is
apple.com
If pasted in Firefox(since Google Chrome has fixed it).

For better explanation, I'll write the whole article on my website.

My bad, Google Chrome is yet to fix the "Did you mean". However, the URL is the same as pasted.
