My problem with the "cheater, cheater, CHEATER!!!" accusations online is the effect it might have on new players. While it might be "just joking" or "for fun", it's got to paint the game in a negative light for those who are just trying it out. There is one Knit player who refers to all opponents as "cheaters". It might seem cute to him, and maybe to others, but seems likely to create suspicion for those who don't know the player and the game. Also, there are some who seem to justify every loss with accusations of cheating -- still not good for retaining new players.
Hey, if I'm that guy. Noted. But I only say it to a select few if it is me.
