Earlier quoted context omitted.
Maybe a "fake" email address in their terms is an impossibly invalid one, unowned one that cannot be verified, or a disposable verifiable one? I'm not sure. Fun fact: Gmail address prefixes can optionally intercalate a period between any letters. All accounts though must be remain unique after normalizing case and removing all periods. a.bc@ = ab.c@ = a.b.c@ = abc@, but only one of these can be registered.
That is all email addresses, it’s part of the spec. Aside from broken implementations of course. Periods are optional. Edit: Woops yeah, meant pluses. Dots are somewhat common as optional these days but not universal.

This handwaving tautology is meaningless.
