Hi I have several questions about PNQ

1. Why does my profile not show up when searched for by Google?
2. Is there anything that can be done to change that.
3. Are our works in anyway protected when we submit them to this website
4. If so how.
If not then what would happen if someone were to copyright their material? Or would want to.
Where does the user sit when it comes to copywrite but also protection.
Does Poems and quotes own everything submitted? How does this all work exactly?
