How to spy on Drupal related domain names

I recently found an interesting service called Mark Alert by Domain Tools.

Mark Alert by Domain Tools allows you to be alerted when someone registers a domain name with any terms or phrases in it that you specify.

Emails are sent daily and you can adjust which terms get emailed to you and which ones don't. Supported TLDs are .com, .net, .org, .biz, .us, and .info.

You can monitor one term for free. I registered myself at Christmas and since then about 50 new domains with the term “drupal” in them has been registered.

It is also interesting that currently there are about 1000 registered domain names with the term “drupal” in them. That's quite a lot, isn't it? But this number includes only .com, .net, .org, .biz, .us, and .info TLDs, so actually there are more. (The funniest domain name is joomlamambooscommercewordpressdrupal.com. LOL.)

Here is a screenshot illustrating how an alert looks like (yes, 17 new domains only yesterday):
