If I wanted to post peachy girls on usenet which group should I use ???
I don't really know, but you can often find pictures of MET girls posted in alt.binaries.pictures.erotica and sometimes in alt.binaries.pictures.nude.
The first has a huge volume of posts, so things might get lost in there.
And is there a code for nude pics and pics with penetration ?
Not sure. It looks as if most people who post to usenet make their own decisions about such things.
Would the mods be happy if people who posted pictures of "our" girls, or who found them on usenet, reported them here?
