If a player is a problem he should be reported. The report feature is on the roster for your convenience. Then HTC can see if it's friendly taunting, an occasional bad day situation, or if it's a toxic player that would improve the game by leaving.
To add to FLS' above post, when a player feels it a need to report another player that is or might be being abusive, the player doing the reporting should right-click the abusive player's gameid and click both the .report text and also right-click the .report voice, if they are doing it over Vox!
If I remember correctly, as guncrasher/semp posted earlier, you should use the 2 report options quickly, because it does trigger a flag to record/copy the text buffer something like 10 to 15 minutes before the report through 10 to 15 minutes after the report....best I recall from how HTC explained it years ago....during one of the many many other threads started, just like this thread...
