I sell porn online to a 12 year kid for bitcoins or whatever and my ass goes to prison and I may even end up on a sex offender registry for the rest of my life.
I care about age verification.
And a lot of these IPOs - if the buyer is not of legal age, technically it may be illegal for you to sell them your coin as an IPO investment. At least in the United States.
I assume that when somebody access a porn site they are told "ADULTS ONLY" if they click " ENTER HERE" it's there own responsibility. A Bitcoin transfer doesn't contain info like (age, gender etc) and that's what makes it right. It's parents responsibility to take care of their kids, nobody should have a say in it unless the parent are doing wrong. If a kid of 12YEARs invest in our IPO, I take my hat off to her/him because they are doing way better than I did at that age.
