When playing online games, it's already common knowledge that there are times when you have to put up with some rudeness, bad manners and irate tempers.
Even if some game communities are more tolerable than others, this is the kind of behavior that is expected of every multiplayer game online. Anonymity is one of the key factors why most people have the guts to display such rude behavior. However, this is not enough of an excuse to forego proper manners and good conduct.

Here are some tips on how to maintain proper decorum in online games:

Be a Good Sport- Do you think laughing at your opponents and bragging your wins make you a good sport? No, these are things that only immature people do. So just play it cool.

If you win, don't slap it on the face of your opponent; be humble about it. If you lose, don't take it too personally. Don't call them cheaters just because they won. Be careful not to throw accusations that you can't support. You have to accept the fact that there can be better players out there.

What you can do is practice more.

Play Fair- If you value winning, then you must understand the significance of a fair fight. Using foul words just implies that you can't play win without playing dirty. What you ought to do is to keep practicing and learn from the pros.

If you feel that you can't handle the competition, then it's probably better to just look for a different game, rather than to cheat your way into success.

Don't Spam- Spamming can really be annoying. You don't have to flood the chat system with WTS messages to sell an item.

If people aren't responding to your messages, it just means they're not interested. Avoid repeating your message in chat every 2 seconds. If people are not paying attention, wait a minute or two, so you can reach to a new audience.

You were once a Noob Too- There are tons of acronyms and slangs involved in every game.

You can't expect everyone to know them all, especially the newbies. Instead of shooing them away and calling them noobs, help them out. Remember, you were a noob too.

Don't be a Quitter- There are people who make the bad habit of suddenly disconnecting from the game without even letting the others know.

This is an example of rude behavior. If you think your chances of winning are scarce, try to work it out by giving some advice to a teammate or the team in general. Try to do this without offending them.

Put in Mind that you're in a Team- You have to cooperate with your teammates a little.
If winning is important to you, don't be selfish and focus the limelight to yourself alone. You wouldn't know, one bad move and you're game is done, just because you refused to work with the team.

Ignore Insults- When opponents insult you, just ignore them.

Insulting them back isn't the best option, Or else, you'll just look as pathetic as them. If the insults persist, you can choose 'ignore' functions that are available in some systems. It's better to block negative vibes than welcome them.

Enjoy the Game- Games are supposed to be fun. You don't have to take everything to heart.
