Dumb Question: why do some avatars say "this place intentionally left blank"?

[La Lioness Priyanka]

is it because the person doesnt know who they are supporting for the primaries?

1. That in itself

is an avatar in the ones
DU has provided to choose
from if you do not upload
your own.

2. It parodies certain military stupidity.

Many classified and otherwise restricted documents contain some blank pages, and accountability requires that each be so labeled, so that an inventory doesn't set off missing-pages alarms.

3. Some textbooks are printed like this too.

4. Actually, many Federal documents are labeled that way too.

In one of my old jobs when we wrote reports for some government agencies, no page could be submitted blank or unnumbered.
