Sometimes you just have to see the world from this big firms point of view, facebook got criticize for making the scams easier for the scammers with their support of crypto related ad. At a point in early 2017 I had to stop using Facebook because the ads scams where just everywhere and you can easily see innocent victims as they share and comments on this ads without any knowledge of what they're engaging themselves in.

The decision of facebook to block all crypto related ads was just the best they can do as you don't expect them to start investigating to know which project are the authentic or scammy ones. In some scenario, project starts off as legitimate but with time their true colours get reviewed.

We're encourage to carry-out personal research before investing but that's not using the case with noobs joining the industry due to the hype of a certain trend like ICO and defi etc.
