Re: IP exclusions
Well if you used IP Exclusion tool with this certain IP address you wont get any clicks from that.
Is it the IP address or IP range? usually most of the ISP companies here use dynamic IP addresses so you can't exactly tell whether it's a person or shared IP address with large group of people
However If you block static IP address using IP exclusions tool you shouldn't see anymore clicks from that
Also just for you information, Multiple clicks from the same IP address cant count as invalid clicks! at least not always
