Scam projects will always find a way to scam people. Craigslist, facebook groups, phone calls, emails, etc.
The bigger issue is that google which controls most of the world's advertisement revenue is deciding to ban all ads.
They will sell banner adds for porn, guns, gambling alcohol and casinos, but are restricting crypto currency ads because they deem them injurous to others well being.
They are getting hammmered in other areas and just didnt want to deal with some new issue.
