There are bigger issues to consider regarding your question:
- Why isn't this hypothetical small child being supervised on the internet, while clicking on "click to reveal" content?
- I remember the day I found my dad's Playboy collection. It was boss. I was 12 years old.
- Little kids masturbate. I'm sorry that's an uncomfortable fact for some adults, but it's not like you started jacking off on your 18th birthday... and if you did, I honestly feel sorry for how repressed your upbringing was.
- If a kid made it through the sign-up process for Steemit, that kid kinda deserves to see it. lol. You can literally type "porn" into Google and see all types of shit.
- There are worse things to behold on the internet than a pair of titties.
