There is an opt-in: http://cdn.crowdprocess.com/opt-in.html (only one website requested it so it's not in English so far).

It's as immoral as advertising, maybe even less. In advertising you show up at a web page and see tons of things that you did not want to see or did not bring you to that web page, sometimes shift your focus and annoys you. It's the same with CrowdProcess, except instead of annoying you, we annoy one CPU core. We believe that while being more expensive than traditional datacenter grid computing, it may be less expensive because it only has to outperform ads. We don't compute on all the CPU cores, of course, only on one.

We actually ask websites to tell they're a part of this, but we cannot control what they do because they can simply display:none.

You could certainly just check to see they're using it properly. Do a screen scrape or even have someone hit the page every month or two, ban anyone abusing it by not notifying users.

that may be harder to do efficiently than building the entire platform and we're an extremely small team. I'm sure some day we'll do it but can't prioritize that now.

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).

You've actually managed to convince yourself that, haven't you?

It isn't because:

1: the user is paying for the electricity being wasted by you. A tab left open could be significantly detrimental.

2: it will cause real problems for mobile users who will be wondering why their battery's flat.

We -really- don't want to seem sketchy and immoral. We plan to stop computing after a certain amount of time (still to figure out, so far we don't have that many tasks running for it to be significant), and we completely block mobile phones and tablets while the Battery Status API isn't present in all devices (http://www.w3.org/TR/battery-status/ only Firefox implements it currently)
