It would be interesting, it could probably be done with browser fingerprinting. I would wager that some of the larger companies have done this.

Personally, it's a question of what the content is. If it's a summary of objective facts, I'm not disabling my blocker. I can probably find the same facts elsewhere that doesn't require me to disable my blocker. If it's an intriguing analysis by someone respected, it's higher value content to me and I likely won't be able to find the same content elsewhere unless it's been stolen.
