Scratch is a platform for all ages, I would even guest that the users of Scratch don't want to see sexual stuff, like myself when I use it as a kid. In the rules they put that they don't allow stuff that "Contains sexually explicit or graphically violent material"
Viewing post in Scratch is unfair
Is that what they have verbatim in their rules? Contains sexually explicit or graphically violent material
Because, well, that would allow sexually non-explicit and non-graphically violent material.
I assume this was about lgbt stuff, that op did not approve of and started a flame war over it. So let's not continue any flame wars here.
