So, picking the metadata battle:

Its straightforward from the command line to email crypto-content to your desired addressee while emailing(spamming?) to a few more auto-generated others. These newly(if functional) spammed others would value your contact, as it provides them with a participating valid email account, so `spamee' can now also `shotgun' emails to more addressees further obfuscating his intended addressee(s). If this became popular, universal, The graph of all our email metadata (nodes?) becomes chaotic.

The timestamp metadata? Send to subset random sampled addressees over set random offset ranges.

The SUBJECT: header could be automated to filter through all this new junkmail.

What else, hmmmmnnn...
