Actually, the best way to stop someone from ban evading is to unban him. C'mon, it's a game give them chances, in case they still continue than just unban their real accounts and make a short script like this:

pawn Код:

new Fucker[MAX_PLAYERS];

public OnGameModeInit()
{
    SetTimer("Fuckyoubanevaders", 60*1000, 1);
    return 1;
}

public OnPlayerConnect(playerid)
{
    if(playerid == banned) Fucker[playerid] = 1; //make ur own saving system for this variable
    return 1;
}

forward Fuckyoubanevaders();
public Fuckyoubanevaders()
{
    for(new playerid; playerid < MAX_PLAYERS; playerid ++)
    if(Fucker[playerid] == 1)
    {
        SetPlayerHealth(playerid, 0);
        GivePlayerMoney(playerid, -25000);
        //and so on..
    }
    return 1;
}

but do not let them know about this secret code, if they ask just tell them it's a bug.. they will stop playing ur server themself..
