Brazilians are frequently depicted as stupid beggars with a pack mentality, and that despite their perceived stupidity, I have heard or read a lot of anecdotes about how they've cunningly cheated other players out of items or in-game money, etc..
Here's a comic that floats around the internet a lot with a lot of the depictions that show up frequently. ("BR?" standing for "Brazilian?" and "huehuehue" is considered to be a distinctively Brazilian way of writing laughing; ie: "hahaha" though I've never actually seen it used myself)

What do you think of in-game racism? Have you encountered it? What do you think the logic of it is? I think it's very interesting that real-world prejudices can carry over to situations that are in theory unrelated, as in "Bow, nigger," and I am also fascinated that new prejudices can be created based solely on in-game behavior, as with gold farmers and Brazilians.
