We had someone crawling over our HKP server (blackhole.pca.dfn.de)
in January or February this year. Because the host is already
quite slow, this had a remarkable impact on the performance (so
it was nearly a DOS attack). So having a robots.txt is definitely
a good thing (then you can at least blame the robot owner).

Recently we have seen another interesting scenario: Encrypting
email gateways initially try to fetch a key for every email
that is sent out (to be correct: for each recipient). They
seem to cache these keys or the information, that no key
existed for a recipient), so this storm of queries settles
down after a few days. In Germany the big car manufacturers
(Daimler-Chrysler, VW/Audi) seem to demand that their
suppliers use these gateways, so we expect increasing traffic
like this in the next years...
