PHP Code:

public void OnPluginStart()
{
    HookUserMessage(GetUserMessageId("TextMsg"), TextMsg, true);
}

public Action TextMsg(UserMsg msg_id, Protobuf msg, const int[] players, int playersNum, bool reliable, bool init)
{
    char buffermsg[512];
    PbReadString(msg, "params", buffermsg, sizeof(buffermsg), 0);
    
    if (StrContains(buffermsg, "#SFUI_Notice_Match_Will_Start_") != -1 || StrEqual(buffermsg, "#SFUI_Notice_Warmup_Has_Ended", false))
    {
        return Plugin_Stop;
    }
    
    return Plugin_Continue;
} 


This will block these messages:

• #SFUI_Notice_Match_Will_Start_Chat (>> Match will start when warmup has ended.)
• #SFUI_Notice_Match_Will_Start_Waiting_Chat (>> Waiting for all players to connect.)
• #SFUI_Notice_Warmup_Has_Ended (> Warmup has ended.)
