Worried about ever growing bans on Google Glass, Google publishes 'how not to be a Glasshole' FAQ.

38. No, you see, I'm not telling you what you're doing with them.

I'm asking you. You know what you're doing with them. I don't. And neither do the people you are "snapping." I don't have to THINK about what you're doing with them. If you photograph me, I will ask you directly what you are planning to do with them. Won't that be a surprise? And then, you'll be surprised to find that I do not want you to do anything at all with a photograph of me. I do not want you to hang it in your living room. I do not want you to post it on your Facebook page or anywhere else. I didn't want you to take it in the first place.

I will ask you, politely, to delete it from the memory on your camera in my presence, and I will expect you to do so. These days, Google will go and look for photos that are similar to another photo. I can, if I wish, find most photos of myself on the internet these days, by asking Google to compare a photo I have and see if it can find others.

So, I ask why you are taking photos of individuals you don't know and what you intend to do with them. You said "art." Well, what will you do with your "art?" Will you exhibit it? Sell it? What? If you do any of those things you need a release. Will you publish it on the Internet? Well, if I find a photo of me, I will ask that you remove it. And you'll need to do that, because you do not have permission to use my image to make money, promote yourself, or for any other reason.

Nor do you have permission from any of those people you "snap."
