I have a domain sbed.ca (not sure why I even own it) and it is listed at GoDaddy Auction and it's home is at dan.com
This morning I got this godaddy auction notification even though I never viewed or watched sbed.com
So basically godaddy is matching words to extensions and hitting up potential bidders who already own the domain in different extensions.
Kind of reminds me of the emails we all get....
I noticed you have domainA.ca and was wondering if you would like to buy domainA.com?
I keep thinking those emails from both parties annoy me but a part inside of me likes getting them in case a hidden jewel ever crops up.
