Well i don't know perfectly about good system that detect the airbreak hacks , but you can follow that for the Anti weapon hack , working awesome. Also you can set an admin command that give guns without making the player get ban just use

pawn Код:

ServerWeapon(playerid, weaponid, ammo);
//instead of using 
GivePlayerWeapon(playerid,weaponid, ammo);

So your command should look like that ,

pawn Код:

CMD:giveweapon(playerid, params[])
{
    new id,weaponid,ammo;
    if(sscanf(params, "uii",id , weaponid , ammo)) return SendClientMessage(playerid, -1, "{FF0000}Usage: /giveweapon [playerid] [weaponid] [ammo]");
    ServerWeapon(id, weaponid, ammo);
    return 1;
}
