Funny, now they serve a different robots.txt:

# cat robots.txt.8-17 # robots.txt Tagsueber von 8-17 Uhr # Disallow robots thru 17 User-agent: kmcrawler Disallow: User-agent: * Disallow: / Disallow: *ROOT=1161830$ Disallow: */servlet/PB/-s/*

Apart from that, I'm not sure about the ROOT and servlet lines. They look like patterns and not like URL path prefixes. Robots don't have to implement pattern matching, and most probably don't, even if Google's does. So many robots may consider this lines junk, and simply ignore them.

With the 17-8 robots.txt, only EmailCollector and GagaRobot are excluded from the entire site, and all other robots are expected to avoid only URLs containing the ROOT and servlet patterns. Robot without a pattern matching engine will see that two lines as junk and ignore them.

With the 8-17 robots.txt, only kmcrawler is allowed, all other robots have to avoid the site.

From the text fragments it is obvious that you are expected to spider only in the night, and that you should behave. Don't collect e-mail addresses, don't waste server resources, don't cause large server load.

There is an imprint claiming some (equivalents of) copyrights, especially non-private use of the layout and the content is prohibited, except for press releases. There is also a contact page that you should use when in doubt.

Rough translations of the text fragments:

von 17-8 Uhr
from 17:00 to 08:00 (local time in Germany, I think)
email Sammler draussenbleiben
e-mail collector(s) stay outside
Robots die durchdrehen fliegen raus
robots running amok are kicked out
Tagsueber von 8-17 Uhr
during the day from 08:00 to 17:00


Today I will gladly share my knowledge and experience, for there are no sweeter words than "I told you so". ;-)
