Children aren't suppose to be on Facebook, or they are suppose to be on the children's version.
And the same logic would apply to steemit if there are children on Facebook they are here as well.

Additionally I don't think your example is very accurate or fair. You're like discounting all of the adults who don't realize a lot of this kind of stuff is happening. And in a sense they may be infantile in their ignorance, but it is no reason to deny them of that knowledge.
