[Plugin: podPress] Stats patch suggestion

I would recommend podpress_functions.php to change the podPress_StatCollector function as follows to prevent counting duplicates. I made the change to my own site because it was attacked by some robot and making our stats numbers unbelievably high..

function podPress_StatCollector($postID, $media, $method) {
		global $wpdb;

		$media = addslashes($media);
		$method = addslashes($method);

		$ip = addslashes($_SERVER['REMOTE_ADDR']);
		//$cntry = addslashes(podPress_determineCountry($ip));
		$cntry = addslashes('');
		$lang = addslashes(podPress_determineLanguage());
		$ref = addslashes($_SERVER['HTTP_REFERER']);
		$url = parse_url($ref);
		$domain = addslashes(eregi_replace('^www.','',$url['host']));
		//$res = $_SERVER['REQUEST_URI'];
		$ua = addslashes($_SERVER['HTTP_USER_AGENT']);
		$br = podPress_parseUserAgent($_SERVER['HTTP_USER_AGENT']);
		$dt = time();
		// -- mod begin --
		//
		// check the db for existing stats record (media file, IP address and datestamp) before counting
		$last_day = $dt - 86400; // so the request within a day will be found
		$e_query = "select * from ".$wpdb->prefix."podpress_stats where media like '$media' and remote_ip like '$ip' and dt >= $last_day";
		$existing_rec = $wpdb->get_results($e_query);
		if ($wpdb->num_rows == 0) // if request for the file from the ip address is not made in the last day, it should be counted.
		{
		// -- mod end --
		$query = "INSERT INTO ".$wpdb->prefix."podpress_stats (postID, media, method, remote_ip, country, language, domain, referer, user_agent, platform, browser, version, dt) VALUES ('$postID', '$media', '$method', '".$ip."', '$cntry', '$lang', '$domain', '$ref', '$ua', '".addslashes($br['platform'])."', '".addslashes($br['browser'])."', '".addslashes($br['version'])."', $dt)";
		$result = $wpdb->query($query);
		return $wpdb->insert_id;
		// -- mod begin --
		}
		else return false;
		// -- mod ends --
	}

It is just a quick and dirty fix to stop the attacker. Please feel free to include or modify the code.
