The frustrating thing about this is that it's still extremely common for people to spam the n-word over voice chat, that's been a problem for years, and I haven't noticed any significant progress in reducing their numbers.
Oh, even more frustrating about this is, the game has a swearing filter enabled by default. If those players saw swear words from me, they quite literally specifically opted into that by turning off the swearing filter! Meanwhile they were allowed to sabotage the game for me and ruin my night AND get me chat-banned.
I play DotA, which seemingly does nothing (at at least, very little). I eventually decided to just disable text and voice chat entirely rather than put up with salt in every other game. Toxicity is contagious.
When i was small it was the normal word to refer to black people, but USA has decided that's racist so now it's "persona di colore", even though as a child i've always found it funny because every person is of some colour :D
