We will have a problem too with tagging posts of NSFW content.
I'm just wondering if strategically is good in the future to attract this kind of content, and it's good to see proposals of mechanisms of prevention
And when I'm "steeming" I have my 3 year old kid always looking and asking about the pictures and he already reads some stuff ...
I don't know if he understands the Icon NSFW content, but I'll have to explain it to him :)
