Can old UseNet threads be changed or added?

Is there a way to predate a UseNet message so that it looks like the
message came from five years ago? Including on everybody's server,
and so on, so that it looks real. Also assuming that the message you
want to change or add is within a thread with multiple reply authors.

Wondering how difficult, if possible.

Mainly curious.
Thanks.

The answer is fairly obvious to me, but I'm no expert.

Maybe the fair question would be assuming the post you want to
insert is a single post without reply authors.

Or the question would be how to construct a thread. Fortunately,
that is how I reworded the subject line before posting.

It's trivial to *create* such an article. Maybe it's even possible to
*post* such an article, i.e. that it is accepted on *your* News server.
Maybe *your* News server is even 'stupid' enough to try to send such an
article to its peers.

But there's *no way* that such an article is *accepted* by *other*
News servers, because News server don't accept articles which are more
than a reasonable time (30 days IIRC) old.

Recently, my computer decided to reset its clock to 1 Jan. 2003 - maybe
the battery needs replacing. A couple of e-mails got out with that time
stamp, but I don't think I made any usenet posts before I corrected it.

Even if the message were (hypothetically) accepted, the article number
would give the OP's game away. The article number would be in sequence
with current articles, not in sequence with articles 5 years old.

No, you can't change a usenet message after it has been posted. Even
if it is still available from servers you can't get a copies on
clients.

The chain of reference headers would be another major clue
indicating a message with a bad date, not an old message.

If you just left off the reference header then it would be a post
with a bad date that starts a new thread.

What kind of clue do you mean, given that the poster can put any and
all MIDs in any sequence in his "References:" header?

Why would the poster do that, instead of forming a proper References
header so it'll thread properly on any server that hasn't expired the
articles in the long dead thread that accepts his followup article with
the bad date. But I'm not sure what Mike's getting at either.

The new post would have the chain showing that post is new, but
all of the others that might still be available would have a
different chain. Changing the reference chain on those other
posts would be an involved, expensive and probably fruitless
enterprise.

In the thread tree, it would show up as the end of a branch, same as
any other followup that itself wasn't a precursor article to another
followup.

Rather than changing references headers on actual articles in that thread,
wouldn't you create a bunch of sock puppets to post followups to that
article?

If the goal is to fake a post that looks like it was part of the
thread from some time before it was actually posted, then it will
have to have a references chain that puts it in the proper place.
As you noted, this will either be at the end of a branch where
the false date will be more evident or at the start of a
subthread filled by sock-puppets where it will be slightly less
noticeable, but just as easily identified as an attempt to
manipulate the thread.

Creating a false chain with legitimate posts appearing to follow
his will be at odds with the reference chains on all other posts
and be proof of a deliberate attempt to manipulate the tread.

Is the OP trying to reuse an old Message-ID to accomplish his
nefarious purpose? That would force it to be threaded, but as no
article in followup to the Message-ID would actually reference the
substituted article, it would still look obviously fake.

There's no way to tell that from the OP, and there's no way to tell it
now. Maybe out of mere idle curiosity someone asked about how to
do something whose only practical purposes are nefarious, maybe not.

It's certainly no crime to spend your time wondering about how to do a
Bad Thing, but if you go around talking about it and asking questions
about how to do it, you can't blame people for thinking you want to do
the Bad Thing no matter how often you tell them you don't.

My question was not about how to forge a post, I asked whether it
was possible and how difficult it might be. Everybody else
exercised their freedom of speech and talked about how it might be
done. That's okay too IMO FWIW, but it doesn't suggest anything
about anybody.

If his Message-ID and References header fields are copied from the
original article, then it is harder to identify the forgery.

Of course it suggests something about you. So do your multiple

Crossposting my full headers! Now you've done it! The extra cycles

That can't be called a superseded article, then. Supersede includes
the command to cancel the original article, which won't be executed
given the substitute article would use the same message-ID. No site
willing to accept a superseded article would process that one.

I'll buy your theory that maybe, possible, a site that never received
the original article could accept the one with the forged date and
forged Message-ID, if for whatever reason, it wasn't careful about
parsing dates. However, if it never got the original, it probably
never got any of its precursors nor followups, so who would be fooled?
It would appear to be a followup article without precursors as it
has nothing to thread with.

There was talk about introducing a Replaces header servers could
honor by replacing the old message with a new one having the same mid.
I don't think it ever got into a released draft, just kicked around on
mailing lists.

What gives you that idea? Supersed has the effect of a cancel; it
doesn't contain a cancel, and neither RFC 5536 nor RFC 5537 specifies
matching the Message-ID and Supersedes header fileds of an article
against each other. I agree, however, that they should the next time
they are updated.

I'm addressing a technical issue, not trying to help the OP do
whatever it is that he's trying to accomplish ;-)

Didn't I just write that? Among the actions Supersedes performs is the
cancellation of the original article. Like that better?

It occurs to me, belatedly, that Son-Of got Supersedes wrong. It never
should have been a header. It should have been a command used in the
Control header.

Which is not the new article.

That would conflict with the restrictions imposed on the handling of
control messages.

I don't except quote editing to remove context in a serious discussion,
so I'm not bothering to read the rest.

Again...

I was wondering about disclosure of inventions, not necessarily
for legal purpose or profit. I asked also out of general
curiosity.

An idea can be shot down as having been thought of before,
regardless of the originator's identity. So the only thing that
matters is the difficulty of forging a post or a thread. Again,
not necessarily for legal purpose or profit.

You were clear from the start about your intention to ask about the
feasibility of the kind of fraud you just explained again.

> Again, not necessarily for legal purpose or profit.

That's not incompatible with "possibly for illegal purpose and/or
profit". But you knew that.
