Some houses of are of stuff, expensive relics.. I have been in those. I don't take anything, it's unethical and breaks the explorers code.

I could also go in a shop knowing the owner will be gone for an hour, and there's no camera's. Would it be OK to take from there?

I don't see it as any different.

By the way, I tried to open your website from Safari and Google Chrome but unfortunately it did not open and gave me an alert that it is not safe to open it.

Thanks, the SSL certificate had expired, it's fixed now.
