The last blog/article I wrote took a completely neutral stance on the subject of increasing bans in the game. The response to it was great and the format allowed me to give equal representation to different points of views. The topic of "manners" gets thrown around on forums and reddit and it becomes a factor in games when players feel the need to remind another player about having "manners." Frankly put, it is an unwritten set of beliefs that some players feel others should adhere to in order for players to improve the community. There are some major flaws with this belief that border irrational thinking which often lead to unjust damning of players but there are also some well-meaning ideals and good intentions. This is one of those situations where people try quantify a construct. Honor only has whatever value a person gives it.
This "code of honor/sportsmanship" has players restrain themselves from taking advantage of enemy misfortune such as a lagging player or a disconnect, saying phrases such as good game (gg) at the end of the game and/or good luck-have fun (glhf) at the start of a game and/or encourages them to keep language clean in the game. On the other hand, the players may be forfeiting obvious advantages that could help them win. Players that choose to take advantage such as a disconnect or they trash talk to put their enemies on tilt, they will often be labeled as "bad mannered players" or simply "bm." Both sides argue on completely different points and I will present them as fairly as I can on different subjects.
I do have to present this disclaimer and opinion though. While these situations have two sides to them, they all involve direct in-game interaction. Anything manipulative outside of the game does not count and any of that manipulation is flat out wrong and negative. Things such as DDOS are just flat out messed up on many levels - including being illegal outright. Third party "hack" programs such as aimbots are downright scumbag levels. LoLNexus and LoLKing are definitely grey areas as they do not really affect the game aside from giving information about the players in the teams.
