Worksheetsengine.com is a two month old domain name owned by an individual in Russia. It has roughly 500,000 pages indexed by Google and a homepage PageRank of 2 despite being entirely duplicate content. According to Compete the site gets 125k unique visitors per month but, I have a feeling these visitors all think they’re using Bing.com.

Weird. Looks like the domain name is pointing to Microsoft though:
$ host worksheetsengine.com
worksheetsengine.com has address 65.55.175.254
$ host bing.com
bing.com has address 65.55.175.254
Hey Wysz,
Thanks your comment and hope all is well! I wanted to mention it, because it does seem like a bit of an odd situation.
Any idea how something like this happens? Do you think Google would consider this malicious?
