So they're basically a company doing adwords PPC/CPA (cost-per-action) campaigns and they managed to become public via reverse takeover?
A big portion of the PPC industry has always been shady. I build software for diabetics and constantly came across highly-optimized landing pages promising to cure diabetes for $99. With highly questionable diets or videos.
They buy up all the expensive adwords health keywords (competing with big pharma), so they must be raking in money.
I also have friends who worked as adwords marketers for people making millions selling non-FDA approved health products (for ex. cleansers and skin bleaching products).
