This seems built into pretty much every Google product at the moment; Calendar, Drive, Photos, GChat. Gmail also seems to be letting through more spam in recent years. It's surprising because I thought spam was in some ways in competition with Google; spammers get traffic without buying ads. Are Google just too mediocre to do anything about this?
