A new email-based extortion scheme targets website owners using Google's AdSense program, demanding bitcoin in exchange for not flooding the publisher's ads with bot and junk traffic. The scammers threaten to trigger Google's automated anti-fraud systems, which could suspend the user's AdSense account. Google has stated that it has measures in place to prevent sabotage and encourages publishers to report concerns about invalid traffic. The company also has a help center and a form for publishers to contact them if they believe they are victims of sabotage.
