Tangentially related, but emails are often auto-deleted by 'cloud' email services (Hotmail, Google etc) when the email is sent from a server-side script like PHP mail(), therefore it is not unheard of for emails to be auto-deleted when it is very likely to be spam. I don't know how the iCloud spam filtering works, but I wonder if there is a block filter being run before the check is done to see if the sender is a known contact (to bypass the spam check). 'barely legal teens' seems like a phrase that would almost certainly be flagged as spam. Perhaps this is just a badly implemented spam system at work (which wouldn't surprise me given Apple's reputation for web services)?
