Well, the biggest site of them "Google" that does this seems to have no
problem retaining and mirroring groups in total.
I guess it would all depend on the particular portal's policy and
ability on article retention. If a portal didn't have a large
retention capability (it seems that most advertise a retention of
anywhere of 1 month to 1 year - with Google being the exception at
forever) and they just picked up posts blindly - well thread fracturing
could be a problem. Having worked with a BB software systems myself
(VBulletin - Invision etc) I do know that most of the major platforms
out there only mirror complete threads and drop threads during the
mirroring process that do not have an origin post or cannot be matched
up with an origin post.
On the copyright issue, I seem to remember back when Deja News was
bought by Google there was a big (well depends on who's perspective,
but in reality it wasn't that big) stink over USENET copyright and all
the USENET posts that Deja had archived being sold for THEIR profit.
All in all, about 3000 people made a petition over it and not much
really became of it (Google Groups is still going strong.) As with
Deja, you can write Google and request that any post that "you" are the
author of be removed and they will remove it. There is also the ability
to do a cancel message via newsreader which will result in the post
being removed from the entire USENET. Keep in mind though that a large
amount of news servers out there do not honor the old traditional type
of USENET cancel requests so the poster's message will never completely
disappear.
The majority of forums/portals have the same policy as Google for
removal and many provide reporting/removal request links on each post
so if anyone does not want their posts to appear on any particular site
most likely all it would take is to make the request on each post and
they would remove it. My thinking on this is that if anyone is going
to post something on the USENET, they (should) know well and good that
it is going to appear all over the world. I guess if it is that
important, they could go to all or some of the countless sites that are
portals/gateways such as Google and request removal from each - but
really if it comes to that much of an obsession for anyone, my advice
would be to get a life and a girlfriend!
