Persistent bombardment from Plasmaxx Research

I am still getting bombarded from IP address 82.165.28.20 which is plasmaxx-research.de. My most recent outage was a a more "formal" attack, but my the cause of my first outage on bloghosts was caused by these requests from 82.165.28.20. It's basically a request for my index.xml about 15 times a minute. Not really hardcore and we are now filtering the requests, but still annoying. It might be a hoard of news readers, but the requests keep coming even after we've banned them and redirected the requests back to Plasmaxx. Anyone know who Plasmaxx Research is? There is no contact info on their page or in the whois. I suppose that if it is indeed an attack, the perpetrator is not actually from Plasmaxx Research. Anyway, if anyone knows anyone from Plasmaxx research, can you tell them to please stop bombarding me.

Have you tried to contact their hosting provider? The whois entry lists at least a zone-c : hostmaster@1und1.com
In case you didn't know, you can get more whois info for german domain at www.denic.de, but they only list an address no email/phone ;)

good luck anywys...

The Domain is registered to:

You can't find him in the Berlin phone book.

Wouldn't you save more bandwidth by just configuring a firewall or a Linux kernel iptable to discard the packets coming from that IP address, instead of implementing a "redirect" ?

Although a bit dated,

this nugget

sheds some more light onto that guy. Maybe someone from Germany wants to give him a call?

Don't know why it didn't work adding the url (affiliate link blocker?), but try searching for '"Planufer 90" udo' on Google Groups.
