And how are you exepcted to tell from a picture whether the subject is
14, 15, 16 or 17. two of those ages are legal in any event, yet the
photo could still be of a teen.

Well a group entitled alt.binaries.pictures.erotica.early-teans.firsthair
or alt.binaries.pictures.erotica.early-teans.hardcore would by definition
contain illegal material. There is no way on earth that you can describe
16 as being early teans and anything before that is illegal.

Newsgroups do not "by definition" contain anything at all. They are public
noticeboards, available to the entire planet, wherein anybody can post
pretty much anything without anybody else stopping them. There are no
guarantees whatsoever as to the provenance of anything in a newsgroup, or
the accuracy of any description given thereof, and as the "content" is only
transitory, even if you could be sure of something on one particular day,
it could be gone the next. You cannot therefore assume anything from the
title of a newsgroup, and it would be impossible to block any particular
type of material simply by blocking access to selected newsgroups by name.
Suggesting that this would be possible is the sort of naive argument that
we sometimes hear from polititians that have no concept of how the internet
works, but I would expect people here to be better informed.
