Hello admins,

Please ban this uneducated person called " SMAEL. " we played 2v2, me and Payet and he was with beta (beta is a nice player and a fair one) my ping during the game was 44 and the game was playable, ping went high to 150 for few seconds only then went back to 44-45 and this was during the beginning of the 2nd half, after that ping was stable. in Extra time when we scored the winner "SMAEL." started insulting me as showen in the image below (please check the link) he insulted me and my mom by saying (**** your mom) ( son of ....) he said it in his own dialect (moroccan). 

Here's the link for the image (https://ibb.co/8KnQBk6)
