Here's an example:

httpd-2.0's repository contains 3,603 files, weighing in at about 41MB.
It also has 62 tags and branches.

Let's say that we convert this repository to Subversion, preserving
history.

If some dumb crawler comes along and decides to crawl
httpd-2.0/[trunk|tags|branches], it's going to suck somewhere in the
neighborhood of 2.5GB of bandwidth as it grabs every tagged and branch
revision on it's way to trunk.

Not for auth info... I'm thinking of the cases where people might leave
Indexes on but prevent indexing of directories by placing index.html
files in those directories... but if they forget about .svn and have
Indexes on, people will be able to browse their text-base. Or even if
Indexes are off, someone could just grab the .svn/entries file and have
a nice listing of what's in the directory.
