I think a report Spammer button should be added into the game, or at least add the Report button to inclue spammers as well.
I'm tired of seeing people repeat the same messages many times in a row and clogging the chat box.I can't focus talking with my friends because there messages disappear before i can read and because the noise of somebody saying something keeps annoying me.
Most other games don't tolerate spamming at all and unfortunately it's probably the easiest to do in this one. By pressing the up arrow key while in the chat box retrieves your last message so all you do is press that and Enter one after another and you have an endless stream of nonsense.
Love to see something done about this in the future
