You forgot both ‘Don’t send too much email’ and ‘Fail to send enough email’ as qualifiers, as well.
Which I think is the big thing that hits more people than anything else, since ‘too much traffic’ and ‘not enough traffic’ are not defined and so you can easily be caught by one, then the other, then end up in purgatory.
(This is mostly a Microsoft problem rather than a Google problem, but still.)
Oh no. Where can I buy single-use trash and toxic waste now?
