They're definitely not trying - in any form. I run a marketplace for dogs (i.e. craigslist for puppies & dogs) and scammers are always trying to post fakes ads. They always use Gmail accounts. Every time I ban a gmail address, they scammers will just get a new one. Same scammer/person has created thousands of gmail accounts and Google doesn't care. I have reported this to Google. For the amount of info Google has on people, trivial for them to prevent some of this.
