Sketchy advertisers are all over the internet, and Google is doing everything it can to stop them from scamming users. According to a recent report on the matter, the search giant removed 1.7 billion ads from its advertising platform in 2016, more than double the amount compared to the year prior. The online housekeeping included 68 million ads for illegal pharmaceutical products, 80 million for content that misled and deceived consumers, as well as 112 million others that used trick-to-click methods.
