All that "security" just to fight spam. IIRC it was estimated that globally spammers make $300M per year from their spam. It doesn't seem like much. Somebody joked that it would be better if we just paid them that much to do nothing.
I wonder what the underlying problem is. Gabe Newell once said that "Piracy is not a pricing issue. It's a service issue". I believe this has been proven by netflix/spotify as well. Is spam just a symptom of a much deeper problem? If so what is it? Or is it naive to think of spam this way?
Still applies to games/music and probably audio books.
