Here in Hong Kong, some weeks ago had ads showing up with cartoons of scantily clad girls, Chinese text.
One had pulsating breasts, another - as I recall - had hands opening and closing as if groping away.
I saw on several sites, inc an international newspaper I think; also on mine [blocked them.]
Not sure what they were for - #*$! or whatever.
May have appeared on your sites, too. I believe the targeting was regional, but it mattered little what the content was.
- would be tough for most webmasters to moderate, if not seen in their own areas.
Also, showed very questionable decisions on part of Google's ad team.
