Greetings Adrianmack:

An actual classification list does not seem to be forthcoming but the
first clue I discovered that may give you a beginning base is located
at and lists
the restricted categories of one educational system blocking program

"Adult Content
 Sex Education
 Lingerie and Swimsuits"

This particular blocking program is used in an educational arena for
keeping students out of certain Internet sites.

I also located another site's definition which may be of interest to
you at

"Adult content on ireallywanna! is material that is intended for
viewing or reading by persons aged 18 or over.  It therefore covers
images, representations or descriptions of (or including) nudity,
eroticism, violence, swearing and profanity.  However, on
ireallywanna! this means no more than the type of material that may
commonly be found in the average city 'Main Street' book-store,
magazine-store, newspaper-store, main-stream theatre, cinema, or art
gallery or photographic exhibition. On, the term
'adult content' does not mean pornography!

"Of course, not all categories of art, creativity and talent on
ireallywanna! will carry such material. Most obviously, it may be
found in the Photographic, Painting, Drawing, Sculpture, Video, Model
and Written Work sections, but it may possibly also be found in
Fashion Design, Acting, Comedy and Cartoon sections."

There is a small table of classification used by an Australian report
located about halfway down the page at

It seems that the general "adult content" refers also to gambling
sites, certain chat rooms/message boards and such.  Would a compiled
list of terms suit your needs or are you wanting a specific document
or study that lists something like "These are the classifications of
adult sites:"?

I have searched various key phrases associated with your question and
have yet to find a definitive list.  Any clarification you can provide
will be of assistance in determining the best way to answer your


"web content" classification process adult sites
"web content" adult classification system
"web content" classification system
"adult content" classification
"adult content" keywords

PS  There does seem to be self-labeling criteria for sites located at
the Internet Content Rating Association (ICRA) at  There, about 1/3 of the
way down the page, is an ICRA questionaire which includes the terms
you may be seeking.  If this is what you are looking for, please
indicate thusly and I'll post my findings as an answer.

One possible classification system to consider is the self-organizing
system created by usenet groups.  As a "for instance", groups devoted
to erotica include:

Buy and Sell erotica
Erotic pictures: Amateur
Erotic pictures: Animals
Erotic pictures: Anime characters
Erotic pictures: Armpits

As you can see, proceeding through the alphabet will give you a whole
host of categories (many of which I would hesitate to list here).  Of
course, there are other categories, besides erotica, to choose from as
well (bondage, porn, fetishes, etc).

If you'd like, I can create a selective list of usenet categories as
an answer to your question.  Let me know.

The problem I am having is in finding a more detailed and graded
classification system that describes what is permissible for different
levels of adult content.

At its simplest there is a world of difference between soft and
hardcore porn for example.  But there are also levels of violence and
language. There does not appear to be a breakdown, as there is for
film classifcation for example, that says certain kinds of depictions
of sex or violence or profanity exist at particular levels.

Another simple example I have is for levels of nudity or depiction of


Partial, frontal or

Revealing attire.



Clothed sexual touching.

Non explicit sexual activity.

Passionate kissing.

Explicit sexual activities.

But again the catagories are too broad and this is only one area of
adult content.  I imagined it would have become more systematic online
as it is for film and TV but I am finding similar sources to those
suggested so far.

The categories and definitions do seem rather broad and general.  To
me, there are three main "sex" categories that everything else stems
from: Romance, Erotica and Pornography or perhaps they would be more
basically described as Sense, Sensual and Sensory.  I'm inventing
terms, I know.  lol   It is surprising that no definitive list seems
to exist.  So much of human physical exchange depends on individual

Hello Adrianmack-ga, and thank you for a challenging question.

There is, in fact, just such a system as you inquired about.  

The Internet Content Rating Association has developed a voluntary
system to screen web materials at different levels of
appropriateness/inappropriateness in order to allow distinctions
between hard core and soft core (and no core!) adult content or

They describe themselves this way:

ICRA's dual aims are to: 

--protect children from potentially harmful material; and, 

--to protect free speech on the internet. 

In short, ICRA is about choice not censorship. 


You can read the details of ICRA's operations -- along with the
detailed categories used to distinguish content based on sex and
nudity, violence, language, and certain themes such as tobacco or
alcohol use, drugs, gambling, etc. -- at their site at:

About a third of the way down the page is a heading that says:  "The
ICRA Questionnaire".  This is the part of the site with the most
relevant information for your needs.  Because some of it is fairly
explicit, I have not reproduced it here.  But I believe it should meet
your needs for an effective and accepted listing of categories of
adult content.

Should any of this require additional explanation, please don't
hesitate to post a Request for Clarification before rating this
answer.  I'll be glad to provide additional details, as needed.

I'm very sorry, but as I re-read the entire thread (after prompting
from a fellow researcher) I realize that the "answer" I gave you is
very much the same as information that had already been supplied, in
an earlier clarification comment, by journalist-ga.

I shouldn't have done this of course, but somehow my brain just
bleeped over the fact that the info was already there. apologies to both you and to journalist-ga.  

Let us know if the answer, as given, is suitable, and if it is, I'll
straighten things out with journalist-ga.  If it isn't, just use a
Request for Clarification to let us know what additional information
is needed.

Thank you for your kind words Adrianmack.  I would like to have
claimed the question fee for my research but I didn't want to post my
findings as an answer until you approved it.  Pafalafa claimed the fee

This is rather puzzling, journalist-ga, I though Pafalafa was going to
straighten this out with you.  I am new to this process but I
acknowledged that you came up with the most relevant answer first.  Is
there still a way to correct this?
