It always bugged me that wouldn't ever work in any web browser.
I hadn't heard that variant before; the one which circulated to me at the time was simply http://////.

Which raises an interesting question, because in my "abstract math" class, we are covering the basics of set theory. And we use the notation A\B to represent a set of all objects in A that are not in B.
Now my question is, is my math textbook wrong? Or were people just generalizing?
"Never" is an exaggeration. "Rarely" would have been more appropriate. Pretty much any symbol you care to imagine will have been used somewhere in mathematics by someone; \ is common for set difference, although - is also used.

I recently had occasion to check on invalid email addresses in our database. Most of these were either phone numbers, indications that there was no email address, or email addresses with the @ replaced by a period (or, to a lesser extent, a 2 or simply omitted). But there were a fair number starting with "www." as well, though those aren't email addresses but website addresses placed in the email field. And (I just checked) we have a few like you describe with "www." in front of what is probably the correct email address. But we regard those as valid; it's possible that someone really does have the email address "www.<redacted for privacy>@hotmail.com". Though I know which way I'd bet
