What type of account is more vulnerable to getting banned for click-fraud? owning 1 site averaging around 1500 clicks/day or A network of 300 scraper sites, each generating 5 clicks/day Now each account would be generating the same amount of clicks/day. Could someone clickbombing 1 site of your 300-site network ban the entire network?
Why scraper sites? You'd be lucky to get 5 clicks per day on 300 rubbish scraper sites. But of course theres more change of having something go wrong the more sites you have.. its really a difficult question to answer though, its purely guess work and speculation.
