"if you’re not sure, don’t." This is a guideline that ethical people already follow. At least, until they've asked permission. People who claim to be ethical will do things until they're told not to, claiming that if they weren't forbidden, it's not unethical. The thing is, ethics doesn't care if you were forbidden or not. It's not about rules or laws. It's about doing what's right, and not doing what's not right. Accidents happen, and I'm not saying they don't... But there's a huge difference between doing things that you know are harmful to another party (even though they haven't said so) and doing things that you don't realize are harmful.
