How should newcomers manage their accounts?

Hello everyone, I am a new user, would like to ask you, how should the new user manage the account? How to operate reasonably so as not to be judged illegal?

I am also new here, although i guess it might be a good idea to do the new user tutorial if you haven´t already. Other than that, it might help to understand common Nettiquette.

Having good netiquette involves being mindful of your behavior, avoiding offensive or derogatory language, and treating others as you would in face-to-face interactions.
