Just played vs Camila Giorgi who insisted that I was making the connection lag only when he/she was serving (I wouldn't know how to make it lag. i always play with no other windows open). Then every time I went to serve, he/she would look at replays and go into menus to mess me up. Then he/she started commenting that I was a 'looser', I assume 'loser' was meant. Then would go away and block chat until the next time he/she wanted to call me a 'looser'.
not too bothered, but they were so pissed at something I wasn't doing I thought I should let people know that if you are beating Camila Giorgi, make sure it lags only only YOUR serve or they won't be happy.
