I am using this ping kickeing plugin to learn from, i understand most of it, but there are a few things i dont get anybodies help would be much appreciated.

public client_disconnect(id) {
	remove_task(id)
	return PLUGIN_CONTINUE
}

Telling the plugin to stop checking someone when they disconnect? Am not so sure about this, or how it works.

public client_putinserver(id) {
	iNumTests[id] = 0
	if (!is_user_bot(id)) {
		new param[1]
		param[0] = id
		set_task(30.0, "showWarn", id, param, 1)
	}
	return PLUGIN_CONTINUE
}

When a player connects, if theyre not a bot show them a warning. But i dont understand why/how this is done with param?
