Maybe use BanIP?

pawn Код:

public OnPlayerCommandText(playerid, cmdtext[])
{
  if (!strcmp(cmdtext, "/banip", .length = 6) && IsPlayerAdmin(playerid))
  {
    if (!cmdtext[6])
      SendClientMessage(playerid, 0xFF0000FF, "Usage: /banip <ip>");

    else
    {
      new fcmd[32];
      format(fcmd, sizeof(fcmd), "banip %s", cmdtext[6]);
      SendRconCommand(fcmd);
      SendRconCommand("reloadbans");
    }
    return true;
  }
  return false;
}

Or do you mean only 1 account per IP?
