----------------------------------
This looks like it's been implemented; e.g the "back" button at
http://blogs.cf.ac.uk/ceri only goes back as far as the earliest post.

> Subject: Spider trap in Roller's calendar
> > Hi
> >
> > The calendar in Roller can cause a small problem for search engine spiders
> > since it's possible to page backwards in dates by the calendar. It's
> > actually possible to page pack to the year zero...
> > Ex: http://rollerweblogger.org/page/roller/000104
> >
> > A spider hitting such a "trap" will just continue to page backwards until
> > it
> > "gets tired".
> >
> > There are two dangerous problems with this:
> > - This can cause unnecessary stress on the server running Roller (ex;
> > Yahoos
> > spider make big slurps and do actually not consider if the server can
> > handle
> > it or not).
> > - At some point the spider will "get tired" because such paging will
> > generate a lot of similar pages (when there are no content all pages will
> > be
> > similar) and the spider will then mark the site as "possible spam" due to
> > all the similar pages.
> >
> > I would like to suggest that there might be added a small check which makes
> > the backward paging in the calendar only go back to when the first post was
> > made in the blog. This would cause the calendar to page back to the month
> > when the first post was added to the blog. To be able to page beyond that
> > month does not have any actual interest.
