The above solutions are useless, youre getting these bots joining your server, therefor OnPlayerConnect is called.
All you need is this (which i use): https://sampforum.blast.hk/showthread.php?tid=320649
Include it, then add

Код:

public OnPlayerFloodControl(playerid, iCount, iTimeSpan) {
	if(iCount > 2 && iTimeSpan < 8000) {
		Ban(playerid);
	}
}

in your gamemode code, and you're safe.
