So activate some kind of net nanny on his account (Parental Controls in System Preferences if you’re on a Mac, there’s an option to try to limit access to adult websites automatically, and it can also log all websites visited, iChat conversations, etc. Heck, you can even set time limits and bedtimes. I’d never looked at these controls before, there are more options than I’d expected.) If he’s using your account with nothing like that to keep an eye on things, he could always just clear the browser cache etc. to hide what he’s been doing.
