Hello,
If you got a replay of that mods can review it and issue a chat ban if necessary to the one who was insulting a player.
To enable replays view this guide: http://forum.worldofwarships.asia/index.php?/topic/6646-how-to-enable-replays-repost-from-beta-section/
To know if you have a pink name, your name will simply turn pink in-game. Just like in WoT (if you've played it) your name goes blue. You should be able to see your name in pink in the port if it happens. Also, if a player team kills, you can send a replay to a mod to pass onto staff for action using the same method as above.
