Wow what a shitty thing to do, damn!

No, it wouldnt be evidence of US government overreach, mainly because the US government was not involved, you were basically just exploiting the game itself. The US /just listens/ to more or less everything you send through its networks.

China is a whole different beast, a whole 'nother realm of extremely invasive direct government censorship all throughout their own sort of internal internet within the Great Firewall of China. Combined with requiring internet users to basically now have a government ID that is the only way they can use the internet legally, requiring users to simply use their real names for all their online handles... there is so much control over the internet inside of china it is truly breathtaking, far too much for a currently homeless tech nerd to go into right now.

Anyway, its also not a common thing, ever seeing a chinese player banned for spamming verboten and already flagged material at them in a game, due in large part to... why would an American or European player ever connect to a Chinese server? Ping is terrible, no one speaks English, and video game hacking is extremely common in China, as, for a very long time, the only way they could really get their hands on a lot of video games was by already being an adept enough hacker to even /get/ a video game not made in China... which there were not many of until relatively recently... point is, if you have played enough games that let you connect to serves all around the world, you know that connecting to a Chinese game server is probably a bad idea.
