Dimasik collects base addresses

This morning a letter came:

~~~~~~~~~
Subject: on the site lerpa.ru
From: Dmitry <pro.dimasik@gmail.com>
Date: Mon, 2 Nov 2009 07:28:12 +0300

I would like to buy your site lerpa.ru
write the cost if you sell.

I was surprised because there is nothing on the site except HabroRSS, and he said that he was not interested in selling. After that, I decided to still see who Dimasik is in a search engine.
It turned out that this is a rather discussed topic and a whole wave of mailing lists are sent to the email addresses recorded in whois.

Most likely in this way spammers check whether addresses are alive.
Now I have another idea, namely that it is SEOers who thus attract the attention of webmasters, because The main references to dimasik are on seoshnyh blogs and forums.

In any case, I think you should not respond to this letter.
