Re: I have a code of conduct
With respect, the only issue with your one liner is it's self-breaching. By telling other people not to do something you're telling them (trying to tell them) how to behave, which the line itself forbids...
That only applies if the OP tries to apply it to other people.
This appears to be the OPs personal code of conduct, not a code of conduct the OP is enforcing on others.
