This guy actually have the ability to get a higher score, but he deliberately lose his score by resign as soon as he get in to the game(as we can see his score plunge into the bottom). so he can enjoy the feeling the pleasure of beating the weak.
not just in China ,not just in score of 1000,it happens everywhere, any time.
I really think that he is a shame for our chinese.
Open aoe2.net/#yourprofile before you play and check who you are playing against to when the game start. Resign asap when you see such player. This is only way I can think of. If they dont care about elo then you can’t care either.
