looks something like this:
Because this link just appears to a non-human client like any other page
link, crawlers such as googlebot will attempt to follow it.
At the very least this causes log spam of "Password:" prompt and then
failed password notification, and of course the wasted bandwidth of
having the bots follow all these links, which appear on every page of
It may be possible to keep bots out with a suitable robots.txt, e.g.:
However, this seems to have limited effect even against googlebot.
In general using simple GET URLs for things which have an action (i.e.,
deleting an email from the archive) is bad form. This should really be
done as a proper form via POST, then bots would ignore it.
It might also be nice to document a simple way to remove the link
entirely. This looks promising:
