What's the BEST way to avoid trouble in ranked for new comers?? behavior based

Hi there, i'd like to hear your thoughts on this, it would be really helpful. What are the best ways to avoid trouble in ranked mode for people new to ranked mode? i am already aware of the obvious basics such as "don't flame" and "be polite" for example, but i'm asking for the not so obvious. apparently it seems alot of people are quick to judge and report, alot of people seem to tilt hard and then flame or say "report (insert username here)" for simply not having an amount of skill that meets their expectations. i see things like "stick to bot games" thrown around alot and get quite tired of it.
