Should I report this guy?
why do you make a topic and discuss about this? you have a brain think about it, if you feel offended then report it, if not just move on.. duh
Yes any other basis is fine. But not nationality.

But if u think about it though, ur opponent was factually correct. U have the American flag (so they assumed ur American), and u did lose, correct?
But still, it's a hate crime and they invaded ur safe space. Such shenanigans shall not be tolerated.

the fair play policy should allow you to report him and have the game annulled and your points restored. see how he likes that.
Hi, so I was playing this game and I accidentaly blunder mate. Welp. Right before the guy mated me, he texted "american loser" in the chat. I felt this to be offensive, but I'm not sure if I'm overreacting or not. Should I report him or not?
