fnboelwein.com redirects to http://www.ehow.com/apply-card-credit-online/. As does bankofelgin.com.

Hi There! bankofelgin.com isn't available, but you're still in a good place -- ehow.com. We think we might have what you're looking for.
Both domains have 184.108.40.206 as an A record, which is different than the redirect IP. And both have proxied whois records. However, they all have the same Server headers:

I wonder how many of these domains are out there? I found these two because they happen to both be part of my spam/parked domains training set.
I'm starting crawl #18 to detect and weed out such domains from DuckDuckGo. Each time I start a crawl I make sure I have no existing false positives or negatives in my training set.
Interestingly, every time a lot of domains flip from parked to unparked and visa-versa. These two fell into the false negative category since I wasn't labeling these pages as spam. Maybe I should...
