Great information!  Thanks Brett.  I checked our httpd logs and
immediately found several thousand hits from this subnet, which is now
filtered.

Imagelock could be another name for Cyveillance.com.  We saw an
identical pattern 2 months ago from another IP which had/has no reverse
DNS.  The domain turned out to be Cyveillance and their ISP was (at the
time) Digex.net who forwarded our complaint and followed up twice.
Thank you Digex!

After 3 complaints to Digex and Cyveillance we finally received this
response from Cyveillance:

Recently Digex, our internet provider, forwarded your inquiry regarding
visits to your site from 207.87.178.66.

We provide companies with brand protection services on the internet. To
accomplish this goal we employ search engines / web crawlers to scan the
internet. We are in no way involved with the creation of unsolicited
commercial email. Please see our web site at http://www.cyveillance.com
where you can learn more about our company and what we do.

It appears we crawled your web site as part of our general web search, and
crawled your mailto directories as part of that search. We hope we didn't
cause you any inconvenience.

If you have any questions, don't hesitate to contact me.

However they never did stop scanning our subnets until we filtered
their subnet at 207.87.178.

This subnet still has no reverse DNS however `whois` shows Cyveillance
is now a customer of imaphost.com and namesecure.com.  "imaphost.com"
is already in our IP filter list (all 27 lines of it) for previous HTTP
abuses however namesecure.com is not.  

Call me paraniod but it sure looks like another Cyveillance attempt to
cover their tracks.
