I have written a letter to the Internet partners and I am following up with their recommendation (sent an email to the abuse department).

The person in question is in Germany.

Here is their letter, what is the situation? Any lessons for the Usenet?

Hi Mehran,

If you look again at the bottom you will see the line:

The user making this post is doing so from a computer
using IP address 81.169.155.246
There is a command called "whois" that can be run at any UNIX prompt including
the terminal prompt under MacOS.  There's a command-line version of whois
for Windows that also does the same thing.  Run it like this:

$ whois -h whois.ripe.net 81.169.155.246

As you can see, you can e-mail ab...@strato.de about this.  Since 81.169.155.246 is their IP address, they presumably know what customers of theirs are using their IP numbers, and can take action
on it.

Beyond this, the only time we put up any kind of network block in the web-to-news gateway is if the gateway is used for spamming.  This isn't the case here.

The person who is impersonating you could do the same thing by putting your name and address in MS Outlook and using that to send news through their own ISP's newsserver.

It's generally accepted on Usenet that anyone who posts to a newsgroup using forged identification of another active participant has already lost the argument.  By responding to
them you merely give them the attention they want.  The best policy is to ignore them.
