Why is there still a web archive for the newsgroup?

[Joakim via Digitalmars-d]

I was just googling for some info and I ran across the old web 
archive:

http://www.digitalmars.com/d/archives/digitalmars/D/radical_ideas_about_GC_and_ARC_need_to_be_time_driven_231949.html

Why is this web archive being kept around?  It means that there 
are three different places where any particular newsgroup message 
is archived, the web forums,

http://forum.dlang.org/thread/lkltve$2u2t$1@digitalmars.com

the web archive created by the mailing list,

http://lists.puremagic.com/pipermail/digitalmars-d/2014-May/197973.html

and the old web archive, with its horribly outdated look and 
incorrect formatting of messages.  All three show up in google 
results for D-related topics, likely confusing users about where 
to access the newsgroup.

If nothing else, perhaps crawlers should be told not to index 
those domains, if you still want to keep the webpages around for 
whatever reason, so that only forum.dlang.org shows up on google. 
  I think the old web archive should be taken down, as I doubt 
anybody uses it.
