Who comes up with these? Do you really think they won't check the sha of that text against something? Imagine the 100 billion dollars of "Buy boner pills @ onlinepharmacy.ru" type emails which make the 68.6% of all the email sent worldwide, do they really think that they can top that?

if (mail.sha == "6ead421c0d8c4e36dbe5c4f5b2f14d93fa634da65f024f6440e4cafc13e7d0e4") irs_audit(mail.sender);

If nothing else it makes their server room A/C more expensive.
