When playing some matches, there are those "people" who think they're so cool and spam voice lines over and over again. It's funny at first, but annoying as hell later. This is usually rampant in the Big Lobbies mod since it's hard to keep track of players.
This mod detects voice spammers through flagged voice IDs and warns the player if such an ID is called. It also tells the player the name of the player who is spamming as well as the ID they used. The sound is later muted and your ears are safe again.
NOTE: Not all IDs are flagged. However, you can add in your own flagged IDs in the lib/unitnetworkhandler.lua file. List of Voiceline IDs
