Failures:

  1) PrivacyFilter does not filter invalid emails
     Failure/Error: filter(text_with_invalid_emails).should eq text_with_invalid_emails
       
       expected: "Contact me here: _invalid@email.com"

  2) PrivacyFilter does not filter invalid phone numbers

  3) PrivacyFilter allows country code to be preserved for internationally-formatted phone numbers
     Failure/Error: filter.filtered.should eq filtered
       
       expected: "Phone: [PHONE] !"

  4) Validations can validate more complex phone numbers

       expected #<FalseClass:0> => false

       Compared using equal?, which compares object identity,
       but expected and actual are not the same object. Use
       'actual.should eq(expected)' if you don't care about
       object identity in this example.
