Google is telling us that it has been fighting these rogues with extensive verification procedures, automated keyword blocking, to changing our ads policies but still those bad people managed to sneak in.
So Google has;
" filed a civil lawsuit in federal court against advertisers we believe have deliberately broken our rules. Litigation of this kind should act as a serious deterrent to anyone thinking about circumventing our policies to advertise illegally on Google. As we identify additional bad actors, we will add them to the lawsuit. Rogue pharmacies are bad for our users, for legitimate online pharmacies and for the entire e-commerce industry—so we are going to keep investing time and money to stop these kinds of harmful practices."Good one Google, How about those spammers with similar informatio asking us to visit those sites. You can find them in any GMail Spam folder! :)
