There's nothing worse that a bad sport with an attitude. Or worse, CHEATERS! Follow these simple rules and you wont get the boot.

Play your own game. You may want to help someone or help them see something they can't see themselves. DON'T! It robs them of the learning experience. It also unfair to that persons opponent. If you help, hint, or play charades to help another player you will get the boot.
No computer players! This is a huge ethical violation and if caught you will be banished from the club and Chess.com. There are bots watching you to detect patterns that point to artificial intelligence.
Follow the golden rule. When conversing with others online, in a game or the forums treat everyone well. No need to be a jerk.
Social Media. Refer to the Centrica code of conduct regarding messages posted in social media platforms. You can find the legal stuff here: Using Social Media
Have Fun! Enjoy the game. Although chess can be competitive be the "Loves to win." type v.s. the "hates to lose."

Enjoy!
