Any site that serves up content that will be interpreted by `sh`.

Meaning, what happens if someone decides they want you to lose your home directory? They serve up the content "rm -rf ~". That doesn't even require privilege escalation, but it might ruin your day.

Let me rephrase:

Is dangerous.com a website with fame for such trick or it's just a name example?

It's a name example.
