  • Why it matters: Scammers on social media networks are taking advantage of two weaknesses at the same time.

  • Why it matters: "These are the Commission’s first cases imposing civil penalties solely for ICO securities offering registration violations," the commission wrote in its announcement. It added that both issuers, Airfox and Paragon, conducted their ICOs after the SEC issued its report last year warning the industry that some could qualify as securities.
