Hi Martin, it is guesswork only, but it is very likely, that DTAG did or do use their nameservers to find out who is sticking his nose into what - to trigger alarms looking for moles in their management. So if you are a DTAG customer - and most German DSL-customers are at least indirectly DTAG customers - then you are wise running your own resolver and never querying a foreign forwarder. Not to mention Journalists.
Directly related? I did use the "lame sever" messages to find adware amd malware servers and created dummy SOAs for them. Users told me that speeded loading some sites dramatically. I dont like censoring but my clients told me, no, that is not censoring.
