Everyone has their own opinions of what best to do in any given situation, hence why no such list has been made in the past.
However the list does fill one vital function: It can make certain people more aware of their attitude and cause them to reign their tongue whenever they would've done something bad, and that makes it useful, in a way.
Nice effort, Sindroms. (I know, it's odd, but i'm actually not sarcastic when i'm saying this.)
