Spammers use this technique to deliver ad copy via calendar popups: the user sees what looks like an event notification but the DESCRIPTION or SUMMARY field contains the advertisement. Guard: does NOT fire when the email has a real .ics file attachment — those are legitimate calendar invites protected by the safety system.
