1) Don't sell ads against stuff you don't own.
?
This guy doesn't.
I can't believe we're even discussing this stuff. This guy is clearly in criminal backwaters fencing illegal stuff. How can you even remotely vindicate his behavior? "Oh but there is a layer of redirection between him and the actual source of the content" really doesn't cut it in my book.
Nobody's defending his behaviour; people are pointing out that the way in which the federal government apprehended him was clearly illegal. There are legal ways to stop him from infringing; let's see more of that.

For bonus points, have the script automatically mount your hidden partition (just stick the password in .netrc) thereby alerting 'them' to the fact that you have one.</sarcasm>The automated script itself can't be encrypted, so you've alerted 'them' to the fact that you're connected to that email account, and pointed them to where the encrypted files are stored (even if they can't access the files themselves).
Your machine could be confiscated coincidentally if you're involved in other things that make people angry. In this case, they may just gloss over any content irrelevant to the charges at hand. Anecdotes I've heard seem to corroborate that mode of operation. In such a situation, the email archives and/or the backup script may never come into play anyway.
You could also not use a script and do it by hand every day. It's just a trade-off of risks; you either do it manually each day and allow yourself to accidentally forget a day, or get lazy and let it go for weeks, or whatever, and keep that data in the hands of a third-party where you really have no idea what's going on with it, or you can put a script on your machine, where local analysis of your HDD could reveal you.
Also, there'd obviously have to be some unencrypted parts of this, but you could probably encrypt the part that contains the actual email address. You can just point a cronjob to a script that decrypts the real script and shreds it to your paranoia's satisfaction when done.
If the script can actually run fully automated (i.e., no passphrase needed), then that'd probably be a problem if someone got a hold of your workstation. So it really shouldn't be totally automated, but mostly automated would still be good.
2) Use anonymous or throwaway email addresses only; never connect from your real IP (see i2pmail, hushmail, and good proxying + generic email service)
3) Run your own ad networks, accept payment only in Bitcoins.
4) Encrypt everything vaguely related; all mail to and from your disposable email address should be encrypted, write a script that downloads and empties its contents nightly storing encrypted archives on your machine only. All code and source control and everything else that can be encrypted should be encrypted. See ecryptfs.
5) Profit!
