Got it up and running in less than 30 seconds, does exactly what i needed.
Smart idea the ip block list to avoid bans for abuse by invalid clicks/impressions!
I did a little modify to allow blocking of the whole class because i'm connecting via hsdpa and my ip changes everytime:
.
.
.
$classB = $myip[0].'.'.$myip[1].'.*.*';
$classC = $myip[0].'.'.$myip[1].'.'.$myip[2].'.*';

if ((!in_array($_SERVER["REMOTE_ADDR"],$blocked_ips))&&
(!in_array($classB,$blocked_ips))&&
(!in_array($classC,$blocked_ips)))
{
.
.
.

as far as i can see it works like a champ

thank you!
