He wasnt on my IP but I logged on numerous times from his computer so I figured that was the reason. But now I use a script to stop showing ads after 2 clicks from 1 IP.
Do most of the big Arb/Adsense players use a script to stop over 2 clicks from the same IP? I always assumed Google had measures in place so you don't get banned for things like this.(I understand lerchmo got banned for logging into same IP that clicked)
Like I said before, if this was the case everyone would be getting banned by idiots out there clicking non stop on everyones adsense.
