Really? How many websites are signed up / do you expect to sign up? Can you not spare 5 minutes per site per month to make sure there's a notification and/or opt-in? Or come up with an automated way to check it. Or use mechanical turk and pay somebody $0.50 per site to check for you.

If you can't prioritize something as important as running an ethical (and law abiding - take a very close look at the ramifications of unauthorized computer usage, which I think it could be argued you're doing with this platform) business, then you really shouldn't be in business.

It isn't as much a matter of ability to verify, but to enforce. Currently the platform is supplied by quite a few websites (over 100), and the best way to get them to adequately communicate this is through proper incentives.

The incentives must be: if you do not comply, your content won't be monetized (as would happen with ads).
